Instrument Flying On Aqua Satellite.
For each EOS instrument, there exists a suite of EOS standard data products. Each EOS instrument science team develops, validates, and maintains the algorithms and science software that produces their instrument's EOS standard data products. The AMSR-E Level 1 products are generated by JAXA and distributed to the AMSR-E Science Investigator-led Processing System (SIPS) located at Remote Sensing Systems for processing to level 2A Resampled Brightness Temperatures. These are then forwarded to the Global Hydrology Resource Center SIPS for processing of EOS Level 2B and 3 standard products. The Level 2 and 3 products conform to EOSDIS standards for science data and metadata. These products, metadata, and associated documentation will be archived and distributed by the Snow and Ice Distributed Active Archive (DAAC) at the National Snow and Ice Data Center (NSIDC).
The National Snow and Ice Data Center AMSR-E web site permits a user to select data and/or products and obtain them in a variety of ways. See the web site for more detail.
Satellite Instruments
AMSR (Atmospheric Microwave Scanning Radiometer - EOS) is one of six instruments on board the Aqua satellite, part of NASA's Earth Observing System. AMSR-E provides observations of radiance 6 frequencies in the microwave spectrum, with horizontal and vertical polarizations observed separately. Spatial resolution of the data ranges from 56 km for the 6.9 GHz channels to 5.4 km for the 89.0 GHz channels. The EOS AQUA AMSR-E measures geophysical parameters supporting several global change science and monitoring efforts, including precipitation, oceanic water vapor, cloud water, near-surface wind speed, sea surface temperature, soil moisture, snow cover, and sea ice parameters. All of these measurements are critical to understanding the Earth's climate. AMSR-E is a passive microwave radiometer, modified from the Advanced Earth Observing Satellite-II (ADEOS-II) AMSR, designed and provided by JAXA (contractor: Mitsubishi Electric Corporation). It observes atmospheric, land, oceanic, and cryospheric parameters, including precipitation, sea surface temperatures, ice concentrations, snow water equivalent, surface wetness, wind speed, atmospheric cloud water, and water vapor.
