AMSR-E/Aqua Daily Global Quarter-Degree Gridded Brightness Temperatures
Entry ID: NSIDC-0302

Abstract: The Advanced Microwave Scanning Radiometer - Earth Observing System (AMSR-E) instrument on the NASA EOS Aqua satellite provides global passive microwave measurements of the Earth. NSIDC produces AMSR-E gridded brightness temperature data by interpolating AMSR-E data (6.9 GHz, 10.7 GHz, 18.7 GHz, 23.8 GHz, 36.5 GHz, and 89.0 GHz) to the output grids from swath space using an inverse-distance ...

Quality Extensive quality control procedures are followed in the production of the AMSR-E/Aqua L2A Global Swath Spatially-Resampled Brightness Temperatures (AE_L2A) source data. See the Quality Assessment section of the AE_L2A documentation for more information. The gridding procedure assumes that source data brightness temperatures are legitimate, and performs no filtering of input data based on quality flags.
