CER_CRS_Terra-FM2-MODIS_Edition4A is the Clouds and the Earth's Radiant Energy System (CERES) Clouds and Radiative Swath (CRS) Terra Flight Model 2 (FM2) Moderate-Resolution Imaging Spectroradiometer (MODIS) Edition4A data product, which was collected using the CERES-FM2 instrument on the Terra platform. Please note that only a few variables from the SSF have been included and this product should be used in conjunction with the CER_SSF_Terra-FM2-MODIS_Edition4A product.

The Clouds and Radiative Swath (CRS) product contains one hour of instantaneous CERES data for a single scanner instrument. The CRS contains geolocation, geometry, packet identification, and minimal cloud properties, and TOA fluxes from the CERES SSF product. For each CERES footprint on the Single Scanner Footprint (SSF), the CRS product also contains vertical flux profiles evaluated at six levels in the atmosphere: the surface, 850-, 500-, 200-, 70-, and 0.01-hPa for both clear-sky and total-sky.

CERES is a key component of the Earth Observing System (EOS) program. The CERES instruments provide radiometric measurements of the Earth's atmosphere from three broadband channels. The CERES missions are a follow-on to the successful Earth Radiation Budget Experiment (ERBE) mission. Two CERES instruments (FM1 and FM2) were launched into polar orbit on board the Earth Observing System (EOS) flagship Terra on December 18, 1999.
