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 terrestrial, oceanic, and atmospheric parameters for the investigation of global water and energy cycles.

AMSR-E Level 1A observation counts are processed from Level 0 science packet data by the Japan Aerospace Exploration Agency (JAXA). Each half-orbit data granule consists of observation counts, antenna temperature coefficients, offsets for calculating antenna temperatures, calibration temperature counts, land/ocean flags, time, latitude, longitude, and navigation fields in HDF format.

The data sampling interval is 2.6 msec for each 1.5-sec scan period for the 6.9-GHz to 36.5-GHz channels, and 1.3 msec for the 89.0-GHz channel. AMSR-E collects 243 data points per scan for the 6.9-GHz to 36.5-GHz channels, and 486 data points for the 89.0-GHz channel. Each swath spans 50 minutes. Data are available via FTP.
