AE_SI12 Cavalieri, D. J., T. Markus, and J. C. Comiso. 20030101 AMSR-E/Aqua Daily L3 12.5 km Brightness Temperature, Sea Ice Concentration, & Snow Depth Polar Grids 2 Boulder, Colorado USA NSIDC: National Snow and Ice Data Center http://nsidc.org/data/ae_si12.html 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 land, ocean, and atmospheric variables for the investigation of water and energy cycles. This Level-3 gridded product (AE_SI12) includes brightness temperatures at 18.7 through 89.0 GHz, sea ice concentration, and snow depth over sea ice. Data are mapped to a polar stereographic grid at 12.5 km spatial resolution. Sea ice concentration and brightness temperatures include daily ascending averages, daily descending averages, and daily averages; snow depth over sea ice data is a five-day running average. Data are stored in HDF-EOS format and are available from 19 June 2002 to present via FTP. scientific research Cavalieri, D. J., T. Markus, and J. C.
