DATA AVAILABLE VIA OPENDAP (DODS)

The Open Source Project for a Network Data Access Protocol (OPeNDAP) provides remote access to individual variables within datasets in a form usable by many tools, such as IDV, McIDAS-V, Panoply, Ferret and GrADS. Currently, the GES DISC offers the following datasets through OPeNDAP. (N.B.: not all OPeNDAP datasets work in all tools.)

AIRS
Atmospheric Infrared Sounder (AIRS) Moisture, Temperature, Cloud and Trace Gases:  OPeNDAP Access  More Info
Visible, infrared and microwave sensors provide daily global temperature profiles with accuracy of 1 K per 1 km thick layer in the troposphere and moisture profiles with accuracy of 20% per 2 km thick layer in the lower troposphere (20-60% in the upper troposphere).Version 5also includes profiles ofCO and CH4 in addition to total column of ozone, CO and water vapor, cloud height and cloud fraction, and other atmospheric dynamic parameters
MSU
Microwave Sounding Unit (MSU) Deep Layer Temperatures and Ocean Precipitation Data
Deep layer temperatures and oceanic precipitation rates derived from 16 years of measurements taken by the Microwave Sounding Unit (MSU) flown aboard NOAA's Polar-Orbiting Operational Satellites (POES).

TRMMTropical Rainfall Measuring Mission (TRMM) Gridded Rainfall Data 
OPeNDAP Access  More Info
TRMM is dedicated to measuring tropical and subtropical rainfall through microwave and visible infrared sensors, and includes the first space borne rain radar. The TRMM orbit is circular, non-sun-synchronous, at an altitude of 350 km and an inclination of 35 degrees to the Equator, providing extensive coverage in the tropics.

TOMSTotal Ozone Mapping Spectrometer (TOMS) Daily Global Gridded Data
OPeNDAP Access: Nimbus-7 Meteor3 Earth Probe  More Info

Since 1978 TOMS has been flown on number of spacecrafts for monitoring global and regional trends in total ozone. It has providedlong-term (over 25 yrs) continuous record of total ozone. TOMS also provided measurements of atmospheric aerosols, volcanic SO2, ultraviolet irradiance, erythemal UV exposure, and effective surface reflectivity.


OMI Tropospheric NO2Ozone Mapping Instrument (OMI) Daily Global Gridded Data 
OPeNDAP Access  More Info
OMI is a Dutch instrument flown (July 2004) on the EOS-Aura spacecraft (equator around 1:30 P.M. in ascending mode) to continue the monitoring of global and regional ozone. OMI also provides five major atmospheric pollutants: Tropospheric Ozone, Nitrogen Dioxide, Sulfur Dioxide, Aerosols, Formaldehyde in addition to BrO, Erythemal surface UV-radiation and Clouds.

Modern Era Retrospective-analysis for Research and Applications (MERRA)

The Goddard Earth Observing System (GEOS) Data Assimilation System (DAS) is used to generate meteorological data assimilation products in support of NASA instrument teams, NASA's research programs, field campaigns, and as a contribution to U.S. weather and climate research. In addition to near-real-time products, the Global Modeling and Assimilation Office (GMAO) is using version 5 of the GEOS DAS (GEOS-5 DAS) for a retrospective atmospheric analysis for the satellite period (1979 - present).

Making Earth System Data Records for Use in Research Environments (MEaSUREs)

Through the MEaSUREs Program, NASA is continuing its commitment to expand understanding of the Earth system using consistent records. NASA has begun to deploy new types of sensors to provide three-dimensional perspectives of Earth’s atmosphere and surface. Emphasis is on linking together multiple satellites into a constellation, developing the means for using a multitude of data sources to form coherent time-series, and facilitating the use of extensive data in the development of comprehensive Earth system models.
