TOMS Online Visualization and Analysis

Nimbus-7 TOMS Daily Global 1.0°x1.25° Products

This interface is designed for visualization and analysis of the Nimbus-7 TOMS Daily Global 1.0°x1.25° Products. Users can generate plots or ASCII Output for area average (Area Plot), time series (Time Plot), and Hovmoller diagram. The animation is available only for Area Plot. Selecting here or the Help buttons will open a new window with detailed help. More details about the data are also available.

Alert: A new window may be opened when a link or a button is selected below.


This is non Java/JavaScript version for TOMS Nimbus 7. Click for Java/JavaScript version.
Use text input boxes below the map to specify area; maximum area is -90 ~ 90 and -180 ~ 180.

Data Description

Nimbus-7 TOMS Daily Global 1.0°x1.25° Products

The Nimbus-7 TOMS Level-3 global gridded data set(new version-8) on the 1.0°x1.25° degree grids used here are produced by the NASA TOMS Science Team. The Nimbus-7 TOMS data set covers the data period from November 1, 1978 to May 6, 1993. The data is transformed from the original scaled numbers to physical quantities at GES DAAC before using it in Giovanni. TOMS global gridded data are also available on DVD-ROM in ASCII format from GES DISC DAAC.

Spatial coverage:	Global 90°S - 90°N
Spatial resolution:	1.0°(Lat) x 1.25°(Lon)
Temporal resolution:	Daily
Documentation:	Nimbus-7 TOMS Data
Data access:	Download the original data files in HDF-EOS or ASCII format.

Continued improvement of this online tool, and the production and dissemination of these data sets, depends on you (our users) to let us know how you have used this tool and these data. We are particularly interested in the value of this tool and these data sets to your research. Please send your comments to help@daac.gsfc.nasa.gov or visit the Giovanni Web forum.
