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.)
Atmospheric Infrared Sounder (AIRS) Moisture, Temperature, Cloud and Trace Gases
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 5 also includes profiles of CO and CH4 in addition to total column of ozone, CO and water vapor, cloud height and cloud fraction, and other atmospheric dynamic parameters |
Global Land Data Assimilation System (GLDAS) Gridded Data (GrADS Data Server)
The Global Land Data Assimilation System (GLDAS) is
generating a series of land surface state and flux products
simulated by four land surface models (CLM, Mosaic, Noah and VIC). Current products include a set of 1.0 degree resolution data products from the
four models (1979 to present) and a 0.25 degree data product from the Noah model (2000 to present).

Tropical Rainfall Measuring Mission (TRMM) Gridded Rainfall Data
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. |
Total Ozone Mapping Spectrometer (TOMS) Daily Global Gridded Data
Since 1978 TOMS has been flown on number of spacecrafts for monitoring global and regional trends in total ozone. It has provided long-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.

Ozone Mapping Instrument (OMI) Daily Global Gridded Data
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.
