AMSR-E : ADVANCED MICROWAVE SCANNING RADIOMETER-EOS

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 squared method. AMSR-E/Aqua L2A Global Swath Spatially-Resampled Brightness Temperatures (AE_L2A) input source data are used to create the gridded brightness temperature data.

These data are provided in three EASE-Grid projections (north and south Lambert azimuthal and global cylindrical) at 25 km resolution. Spatial coverage is global, data are daily, coverage begins 19 June 2002, and processing is ongoing.

Data are provided via FTP as they become available. Brightness temperature data (in tenths of kelvins) are two-byte unsigned integers and time files are two-byte signed integers.
