AMSR-E/Aqua Daily L3 6.25 km 89 GHz Brightness Temperature Polar Grids  View Catalog Page Entry ID
AE_SI6
Summary
The Advanced Microwave Scanning Radiometer - Earth Observing System (AMSR-E) instrument on the NASA Earth Observing System (EOS) Aqua satellite provides global passive microwave measurements of terrestrial, oceanic, and atmospheric variables for the investigation of water and energy cycles.
This Level-3 gridded product (AE_SI6) includes brightness temperatures at 89.0 GHz. Data are mapped to a polar stereographic grid at 6.25 km spatial resolution. This product is an intermediate product during processing of AMSR-E Level-3 sea ice products at 12.5 km and 25 km resolution. All variables include daily average, daily ascending and descending horizontally and vertically polarized brightness temperatures. Data are stored in HDF-EOS format and are available from 19 June 2002 to present via FTP.
