Introduction

The Multi-sensor Aerosol Products Sampling System (MAPSS) has been established as a consensus data framework for multi-sensor aerosol validation, intercomparison, and joint analysis.  MAPSS supports data products from a variety of sensors and instruments, including ground-based, airborne, and spaceborne, obtained at different locations and time around the globe.



 

Quick start

Step 1: Select one or more ground locations (stations)

Tip: locations can be entered either manually by typing in location names separated by comma, or by using the location selection dialog that opens by clicking on the "Select" button.

Step 2: Select one or more parameters

Tip: Hovering with a mouse pointer over items in the Product, Parameter, Layer, or Variable would produce a pop-up with a more complete description of the item.

Step 3: Select dates range

Tip: dates can be either typed in manually using the mm/dd/yyyy format, or by using the calendar dialog that opens by clicking on the calendar icons next to the date range fields.

Step 4: Press "Get Plot(s)" and stand by while data are retrieved

Step 5: Data are displayed on one or more plots

Step 6: Retrieved data can be downloaded as an CSV file

Step 7: Data linage tab provides a summary of the retrieved data

Step 8: Previous results and their data selection criteria can be reloaded if necessary

Tip: "Load" button reloads only the results of past trials. To also reload data selection criteria that were used to produce these results, please press "View Criteria"; until this button is pressed, the "Data Selection" tab will show the data selection criteria of the most recent results.



 

Description

MAPSS provides statistics of spatial and temporal subsets of Level-2 aerosol scientific data sets (SDS) from a range of sensors that currently includes AERONET, MODIS, MISR, OMI, POLDER, and CALIOP.

Certain ground locations, including, but not limited to, the AERONET sun photometer measurement sites, have been identified as focal points for these spatial statistics. The process of generating the statistics for each spatial spaceborne aerosol product involves extracting values of the pixels that fall within an approximate radius of 27.5 km from the chosen locations (see the diagram below).  Similarly, statistics for ground-based temporal observations in a particular location are derived from measurements taken within 30 minutes of each satellite overpass over this location.

This subset of pixels for each location is then used to compute the following statistics:

  • Total number of pixels in the subset;
  • Number of valid pixels in the subset;
  • Value of the central pixel in the subset;
  • Mean of the subset;
  • Median of the subset;
  • Mode of the subset;
  • Standard deviation of the subset;
  • Slope of a plane (for a spatial subset) or line (for a temporal subset) fitted to the subset;
  • Azimuth (direction) of the slope of the plane; and
  • Multiple Correlation Coefficient (for a spatial subset) or Linear Correlation Coefficient (for a temporal subset)

Note that mean, median, deviation, slope, azimuth and correlation are computed only for continuous datasets (i.e., datasets with real numbers). Likewise, mode is computed only for discrete datasets (i.e., datasets with integer numbers). We do not compute standard deviation for a sample if it has only 1 data point. Furhtermore, we do not compute slope, azimuth and correlation if the number of data points in the sample is insufficient to fit a plane; the threshold varies with the resolution of the products.

Statistics for each data product are updated on a daily basis. There is usually, however, a delay of several days between the data availability in a repository for a sensor and its availability in MAPSS, associated with the time required for data retrieval and processing.  Also, there are likely to be some data gaps resulting from non-retrieval conditions encountered by the sensors, including clouds in reflective bands, downtime for sensor calibrations etc.

WEB MAPSS and data production cycle

MAPSS produces and archives sampled data in a form of comma-separated text files; these files are available for download at http://modis-atmos.gsfc.nasa.gov/MAPSS/. A more interactive access to the sampled data is provided by the WEB-based data customization and plotting interface, http://giovanni.gsfc.nasa.gov/mapss/. Using this interface, it is possible to create a custom file containing one or more datasets of interest, sampled at a specific location and at a specific time. It is also possible to display the selected data on a plot, providing for a rapid data exploration and evaluation process. The MAPSS data production cycle, as well as the relation between MAPSS and WEB MAPSS is explained in the picture below.

The data customization interface of WEB MAPSS consists of 3 main sections: station picker, parameter picker, and date range picker. The pickers can be configured in arbitrary order. Still, a selection made in one of the picker might affect the other pickers; for example, selecting a particular aerosol parameter will limit the date range picker to the production dates of this parameter.

The station (location) picker can be configured manually by typing in names of desired stations separated by comma, or automatically by pressing the "Select" button and choosing stations from the pop-up dialog. In the dialog, multiple stations can be selected by holding "Ctrl" key (on Windows) or "Command" (on Mac) and clicking on the station names of interest.

The parameter picker is configured by progressively selecting aerosol product, parameter (i.e., data set), data set layer, and variable (i.e., measurement statistics or geometry value), and clicking the "Add" button. Explanations of an unfamiliar product/parameter/layer/variable data item can be obtained by hovering mouse over this item; clicking the blue "info" button will open the MAPSS documentation at the section of the selected product. Selected parameters are added to the "Summary" area of the picker, and, if necessary, can be removed by clicking the "Delete" button. Note that the parameter picker has two modes: "Basic" and "Advanced". In the "Basic" mode, only the most popular data sets and variables are shown, while the "Advanced" mode displays the full range of the data sets and variables.

Like the station picker, the date range picker can be also configured either manually by typing in the dates, or automatically by using the provided pop-up dialog. Using the dialog, the date can be selected by clicking on an appropriate day; a month can be adjusted to a next or previous month by clicking the arrows at the top of the dialog; a year can be adjusted by clicking on the year label at the top of the dialog (i.e., between the month selection arrows). Please note that some of the dates in the dialog may be grayed out; this indicates that there is no MAPSS data sampled at these dates for the selected stations and products; in this case, it might be necessary to adjust the selection in the station and parameter pickers.

Once the data picker is configured, the selected data can be plotted and downloaded by clicking one of the "Get Plot(s)" buttons. The produced plot can display up to 3 categories of aerosol parameters; if the selected parameters can not be organized in 3 categories, the system will generate several independent plots. After creating a plot, the selected parameters can be adjusted by clicking back on the data picker tab; after adjusting the parameters, click on the "Get Plot(s)" button again - this will create a new plot. Previously created plots can be reviewed by selecting the appropriate item from the "Current Result" list and clicking the "Load" button.

The plotted data can be downloaded as a comma-separated file using the "Download Data" tab on top of the plot page. Note that the produced files can have very long names; if your operating system (e.g., Windows XP) does not support some long file names, please choose a shorter name while saving the file in your browser.

Format and naming conventions

Naming conventions

MAPSS provides subset statistics in the form of comma-separated text files, available for direct download at http://modis-atmos.gsfc.nasa.gov/MAPSS/, or thorough the Web-based customization interface. These files are organized in columns, where the name of each column follows the next conventions.

Generally, names of all MAPSS columns are composed from an abbreviation of a dataset name (e.g., AOD stands for Aerosol Optical Depth) and abbreviations for specific parameters within this dataset (e.g., AOD0550sm stands for Aerosol Optical Depth measured at 550nm for particles in small mode); dataset column names can be expected to be unique within a set of MAPSS files produced for a specific aerosol product. For detailed explanations of the column names in a particular product of interest, please refer to an appropriate product section in this document.

Certain column names can be prefixed with abbreviations followed by underscore, signifying a type of statistics reported in this column. For example, sdev_AOD0550sm denotes standard deviation computed for a MAPSS sample of AOD550sm. The prefixes used in MAPSS are as the following:

cval Data value in the center of the subset
nval Number of valid subsetting points in the subset
mean Arithmetic mean of the subset
sdev Sample standard deviation of the subset
slop Slope of a plane fitted to the spatial subset, or of a line fitted to the temporal subset
slaz Azimuth of a plane fitted to the spatial subset
mcoc Multiple correlation of the spatial subset
lcoc Linear correlation of the temporal subset
medn Statistical median of the subset
mode Statistical mode of the subset


There are also several special column names, common to all data products:

ndat Total number of the subsetting points in the subset, including ones without valid data
orbit Orbit of the satellite while acquiring data in the subset
irowc Row of the original data file containing the central data point of the subset
icolc Column of the original data file containing the central data point of the subset
block Block of the original data file containing the central data point of the subset

File format

Format of raw MAPSS files

Raw MAPSS files are available for download at http://modis-atmos.gsfc.nasa.gov/MAPSS/ and have the following format. The header of the file contains information about dataset sampled in this file, as well as input parameters of the MAPSS sampling algorithm. This includes product (PGE) name and version, dataset (SDS) name and description, surface resolution of a single pixel in the dataset, units of measure of the dataset, number of layers in the dataset (e.g., a dataset containing aerosol optical depth can report AOD at several wavelengths), diameter of the surface circle or time interval used for sampling, and maximum number of data points that can fit into the sample.

The line following the header lists data column titles and uses the naming conventions as described above. The remaining lines contain the actual data. In the data block, leftmost columns list auxiliary information, including date and time of the sensor acquiring the central sampling data point (i.e., the time of the overpass), source product file used to produce the sample, sampling location, line and row of the central sampling data point in the source file, total number of data points in the sample (including ones containing a fill value), and number of layers in the dataset. If available, these columns may also include sensor geometry information registered over the central sampling data point, and mode of data quality flags over the entire sampling area.

Important note: because of the special multi-camera sensor architecture, geometry parameters of the MISR MIL2ASAE product are reported in a separate “Geometry” dataset, and are not included in other MAPSS files of this product.

The remaining columns are grouped by dataset layers. For each layer, the columns list a number of statistical parameters as described in the Description section, prefixed by the abbreviations described in the naming conventions section. In the picture below, green shading indicates sampling locations, while orange shading highlights first columns of layer column groups.

Format of MAPSS files generated using WEB interface

The format of the files generated using Web-based customization interface for MAPSS is the following. The rows 2-3 indicate the range of the dates used to generate the data. The row 4 contains names of ground stations used for the sampling, where each station name cell is followed by a trailing set of empty cells. Please note that all the data located below row 4 under a cell with a station name and its trailing empty cells always belong to a MAPSS sample at this location. Row 5 contains titles for the data columns, and the rest of the rows contain the actual data.

The first column of the data block contains sampling dates, while the rest of the columns are organized in pairs of the form [name of file used to produce a particular data value, the data value]. Naming conventions follow those described in naming conventions section with the exception that the titles also contain product and station names. For example, a pair of column titles [filename_mean_MYD04_L2_051_AOD0550_GSFC, mean_MYD04_L2_051_AOD0550_GSFC] indicates a source file name and a value of aerosol optical depth at 550nm from the MYD05 L2 version 5.1 product at the GSFC location.

In the example picture below, two shades of red indicate two aerosol parameters sampled at the GSFC location, while two shades of green highlight the same two parameters sampled at the SERC location.

AERONET

The AERONET (AErosol RObotic NETwork) program is a federation of ground-based remote sensing aerosol networks established by NASA and PHOTONS (Univ. of Lille 1, CNES, and CNRS-INSU), and is greatly expanded by collaborators from national agencies, institutes, universities, individual scientists, and partners. The program provides a long-term, continuous and readily accessible public domain database of aerosol optical, microphysical and radiative properties for aerosol research and characterization, validation of satellite retrievals, and synergism with other databases. The network imposes standardization of instruments, calibration, processing and distribution.

MAPSS supports three AERONET aerosol products: the standard AERONET AOD product, the AERONET SDA spectral deconvolution product, and the AERONET INV inversion product.

MAPSS processes two levels of AERONET data: Level 1.5 (cloud-screened data) and Level 2 (cloud-screened, re-calibrated and quality assured data). While Level 2 is more accurate and suitable for research, its availability may be significantly delayed; on the other hand, Level 1.5 data are less reliable, but are available within hours of a measurement and appears in MAPSS much faster.

IMPORTANT NOTE: Some of the measurements in the original AERONET data files are reported for several adjacent wavelengths (e.g., 439 and 440 nm), where only one of these wavelengths actually contains data, or is reported for one of the closely adjacent wavelengths that vary depending on the file. MAPSS aggregates this wide set of AERONET wavelengths into a smaller set using the following lookup table:

AERONET_AOD (AERONET_AOT)

AERONET AOD (AOT) is a collection of the standard AERONET sun photometer aerosol products obtained by direct measurement of solar radiance.

*IMPORTANT NOTE: MAPSS includes the "AerosolOpticalDepthInterpolated" dataset that is a derived product, produced in MAPSS by interpolating the original AERONET AOD data using the quadratic fit on log-log scale (Eck et al, 1999). It is not supported by AERONET team, and designated strictly for validation purposes; furthermore, the interpolated data might have certain inaccuracies, inherent to the process of interpolation..

AERONET_SDA

The AERONET SDA data product is produced by a spectral deconvolution algorithm based on the standard AERONET measurements. The algorithm enables discrimination of particles in fine and coarse modes, which is not available in the standard AERONET AOD product. Since only some of the standard AERONET measurements are suitable for SDA, the SDA product has a significantly smaller number of data points than the standard AERONET AOD product.

AERONET_INV

The AERONET INV aerosol product is computed with the help of an inversion algorithm that, based on a limited set of measured aerosol properties, estimates possible values for other aerosol properties. Unlike AERONET SDA product, the INV product is computed from the measurements collected, in addition to the standard measurements of AERONET. In this way, the inversion product provides the most complete set of aerosol parameters, but with the smallest number of available data points.

*IMPORTANT NOTE: MAPSS includes the "AerosolOpticalDepthInterpolated" dataset that is a derived product, produced in MAPSS by interpolating the original AERONET AOD data using the quadratic fit on log-log scale (Eck et al, 1999). It is not supported by AERONET team, and designated strictly for validation purposes; furthermore, the interpolated data might have certain inaccuracies, inherent to the process of interpolation.

MODIS

MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard the Terra (EOS AM) and Aqua (EOS PM) satellites. Terra's orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon. Terra MODIS and Aqua MODIS view the entire Earth's surface every 1 to 2 days, acquiring data in 36 spectral bands, or groups of wavelengths (see MODIS Technical Specifications).

Depending on the satellite, MODIS products have a MODXX (Terra) or MYDXX (Aqua) designation, where XX is a two-digit number identifying a product. MAPSS samples two Level-2 MODIS aerosol and water vapor products: MOD04 (MYDo4) and MOD05 (MYD05).

When working with MODIS data, it is important to pay attention to Quality Assurance (QA) flags supplied with the data. Particularly, MODIS adopts the following data quality conventions:

  • 0 - No Confidence (or Fill)
  • 1 - Marginal
  • 2 - Good
  • 3 - Very Good

     
  • -1 - This is a special value adopted in MAPSS to indicate a flag was not found in the MODIS data, or contained a fill value

Depending on the MODIS product, one of the three flags should be used:

  • QA-l - Land retrievals, the 470nm Aerosol Optical Thickness Confidence Flag
  • QAdpbl-l - Land retrievals in Deep Blue data sets, the Deep Blue Aerosol Confidence Flag
  • QAavg-o - Ocean retrievals, the Aerosol Parameters (Avg. Soln.) Confidence Flag

MOD04_L2 and MYD04_L2

MOD04 and MYD04 are aerosol products produced by the MODIS instrument on board the Terra (MOD) and Aqua (MYD) satellites. The MODIS Aerosol Product monitors the ambient aerosol optical thickness over the oceans globally, and over a portion of the continents.

Datasets in this product are split into two groups - the standard data sets and Deep Blue data sets. Deep Blue data is computed over bright land surfaces (e.g., deserts), where the standard algorithm is not applicable.

Notes:

  • When both "average" and "best" variants of a same data set exist, the "average" variant is usually better.
  • Since land and ocean retrievals use different sets of wavelengths, land-only and ocean-only data sets are usually more preferable and contain more data than merged land-ocean data sets.

MOD05_L2 and MYD05_L2

MOD05_L2 and MYD05_L2 are the precipitable water products consisting of column water vapor amounts from the Terra (MOD05) and Aqua (MYD05) satellites. During the daytime, a near-infrared algorithm is applied over clear land areas of the globe and above clouds over both land and ocean. Over clear ocean areas, water vapor estimates are provided over the extended glint area. An infrared algorithm for deriving atmospheric profiles is also applied both day and night for Level 2.

MISR

The Multi-angle Imaging SpectroRadiometer (MISR) is an instrument aboard NASA's Terra spacecraft. One of the most distinct features of MISR is its ability to view the sunlit Earth from 9 widely spaced angles, which allows MISR to measure a number of aerosol properties that are not available from the other instruments. For this reason, many of the MISR data sets are provided separately for each of the 9 cameras. On the other hand, some of the data sets are a merged product of all or some of the 9 cameras.

MIL2ASAE

MIL2ASAE is a MISR Level 2 aerosol product. It is considered to be a "FINAL" product, meaning that it is more reliable than a "FIRSTLOOK" MIL2ASAF aerosol product, but with a penalty of not being available until several months after the data were acquired.

Many datasets in MIL2ASAE use encoding schemas, where a limited set of integer numbers is associated with some meaning (i.e., 0 = hot, 1 = cold, etc.). A full list of these encoding schemas can be found in MISR Data Product Specifications Document.

When working with the MIL2ASAE data, one should pay attention to the following Quality Assurance (QA) flags:

  • QAb - Flag indicating criteria for establishing aerosol optical depth and Angstrom exponent best estimate and uncertainty
    • 0 = there was 1 successful aerosol mixture; set RegBestEstimateX to value for the single successful mixture; set RegBestEstimateXUnc to fill, except RegBestEstimateSpectral OptD epthUnc, which is set to value of OptDepthUncPerMixture for the successful mixture
    • 1 = there were multiple successful aerosol mixtures; set RegBestEstimateX and RegBestEstimateXUnc to mean and standard deviation of X over all successful mixtures
    • 2 = estimates and uncertainties are calculated by averaging successful mixtures in neighboring regions
    • 3 = there were no successful mixtures; set all RegBestEstimateX and RegBestEstimateXUnc to fill
  • QApprop - Quality indicator flag for single scattering albedo, aerosol optical depth fraction, number fraction, and volume fraction
    • 0 = good
    • 1 = bad

Note that each pixel in MIL2ASAE product corresponds to a 17.6km x 17.6km area. In MIL2ASAE products, this area is referred to as a "region".

Important note: because of the special multi-camera sensor architecture, raw MAPSS files report geometry parameters in a separate “Geometry” dataset, and are not included in other MAPSS files of this product.

OMI

OMI is the Ozone Monitoring Instrument that flies onboard the Aura satellite. The OMI instrument employs hyperspectral imaging in a push-broom mode to observe solar backscattered radiation in the visible and ultraviolet.

OMAERUV

OMAERUV is the Level-2 near-UV aerosol absorption and extinction optical depth and single scattering albedo OMI product.

Because of the large sensitivity of OMI near-UV observations to particle absorption, the Absorption Aerosol Optical Depth(AAOD) is the most reliable quantitative OMAERUV aerosol parameter. Since, by definition, AAOD is insensitive to clouds, the AAOD retrieval can be extended to pixels with small amounts for cloud contamination and is not restricted to completely cloud-free scenes as it is the case for the AOD retrieval.

When using OMAERUV products, it is necessary to consider Quality Assurance (QA) flags, particularly the Qafaf (final algorithm flags) flag that is reported in MAPSS and applied to Aerosol Optical Depth (AOD), Single Scattering Albedo(SSA), and Absorption Aerosol Optical Depth(AAOD) data sets. When comparing AOD from OMAERUV with other data sets, please use the flag 0 only. When comparing AAOD with other data sets, please use both flags 0 and 1. The meanings of these flag values are as the following:

  • 0 - Most reliable (AAOD, SSA, and AOD)
  • 1 - Reliable (AAOD only)
  • 2 - Less reliable for all products

Note that some of the OMAERUV datasets provide data at several heights. These heights are the possible aerosol heights considered by the OMAERUV algorithm (the best-fitting height is reported in the FinalAerosolLayerHeight data set); thus, these data should not be treated as a vertical distribution of the aerosols.

POLDER

POLDER (POLarization and Directionality of the Earth's Reflectances) is a wide field-of-view imaging radiometer that provides systematic measurements of spectral, directional and polarized properties of solar radiation reflected by the Earth/atmosphere system. Since 1996, three POLDER instruments have flown: POLDER-1 onboard JAXA/ADEOS I (November 1996 - June 1997), POLDER-2 onboard JAXA/ADEOS-II (April 2003 - October 2003) and PARASOL onboard CNES/Myriade microsatellite within the A-train constellation (December 2004).

MAPSS supports two POLDER Level-2 aerosol data products: PxL2TLGC and PxL2TOGC, where 'x' can be either if 1, 2 or 3, representing iterations of the POLDER instruments. PxL2TLGC are Level-2 aerosol products over land, while PxL2TOGC are Level-2 aerosol products over ocean.

It should be noted that some of the POLDER datasets are a result of an inversion model fit and produced only for pixels with favorable viewing geometries and conditions. Thus, the quality of the fit should be considered when using the POLDER data; for this, it can be necessary to inspect the following data quality flags and indexes:

  • QAviewgeom - this is a measurement quality index for viewing geometry conditions. The index is a real number in a range between 0 (bad) and 1(excellent). A low index indicates that many of the directional measurements of POLDER are missing or saturated, and might not be sufficient for the inversion.

  • QAinv - this index is an indicator of the quality of the inversion fit. The index is a real number in a range between 0 (bad) and 1(excellent). The higher values of this index indicate that radiances obtained from the inversion models are in a good correspondence with the actual radiances measured by POLDER.

    For the land product, QAinv should be interpreted in relation with QAviewgeom: when QAviewgeom is low, it is easier to fit inversion radiances to measured radiances; however, such a fit might be inaccurate with respect to the actual atmospheric conditions. In such cases, data with high values of QAinv should be treated with extreme caution.

  • pixQbits-l and pixQbits-o - bitfield flags representing a set of pixel quality and confidence data. These flags are 32-bit numbers, where each bit (or a combination of bits) represents a certain metric of the POLDER algorithm. By inspecting these flags, one may learn about result of the inversion, possible errors or difficulties encountered in this process, etc. Please note that the flags have different formats and convey different information for the land and the ocean products, as designated by the -l (land) and -o (ocean) suffixes.

CALIOP

CALIOP (Cloud-Aerosol Lidar with Orthogonal Polarization) is a two-wavelength polarization-sensitive lidar on board of the CALIPSO (The Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation) satellite. The main distinctive feature of CALIOP is its ability to provide high-resolution vertical profiles of aerosols and clouds. Furthermore, unlike other sensors supported in MAPSS, CALIOP is capable of measuring aerosol properties during both daytime and nighttime.

05kmALay

05kmALay is a CALIOP product reporting aerosol properties for both vertical column (i.e., for the complete vertical span of the atmosphere) and distinct horizontal layers detected in this column.

While MAPSS samples column properties in a way that is similar to sampling other aerosol products, sampling of layer properties requires a special processing - please see the image below. To sample aerosol layer properties, MAPSS first identifies layers detected by CALIOP over a data point that is closest to the sampling location. For each of the identified layers, MAPSS checks if this layer spans over other data points in the sampling area. Finally, MAPSS computes its normal set of statistics on the full horizontal span of each of the detected layers.

mapss_caliop_sampling.jpg

Additional information about sampled layers is indicated by the following flags:

  • In 05kmALay v.3, a single atmosphere column may include up to 8 layers; the actual number of layers detected over the central data point and used in MAPSS is reported in the MAPSS column "cNLayers", while the mode of the number of layers over all sampling data points is reported as "modeNLayers".
  • The 05kmALay layers can be of two types: aerosols and stratospheric features; if at least one layer used in MAPSS sample over a particular location is identified as a stratospheric feature, MAPSS sets "flagStratFeature" to 1.
  • The 05kmALay algorithm may decide to extend the base of a layer from an initially assigned altitude to a new lower altitude, which considerable affect the reported values of atmospheric properties; if at least one of the sampled layers is indicated as extended, MAPSS sets "flagBaseExtended" to 1.
  • The "flagDay" is set to 1 if the sampled data was acquired during daytime conditions; it should be also noted that nighttime aerosol layer retrievals of CALIOP are considered to be more reliable than the daytime ones. 

For more information of CALIOP data usage, please refer to the CALIPSO user guide.
