| Summary: | The AMSR-E sea ice standard level 3 products include sea ice concentration, sea ice temperature, and snow depth on sea ice. The AMSR-E standard sea ice concentration product is generated using the enhanced NASA Team (NT2) algorithm described by Markus and Cavalieri (2000), the snow depth is produced from the algorithm described by Markus and Cavalieri (1998) for both hemispheres, but excluding the Arctic perennial ice regions, and the ice temperature is produced from an algorithm similar to the Nimbus 7 Scanning Multichannel Microwave Radiometer (SMMR) sea ice temperature algorithm described by Gloersen et al. (1992). Additionally, the difference between the Bootstrap algorithms (see ATBD by J.C. Comiso) and the NT2 retrieved concentrations (Bootstrap-NT2) are archived. These products together with AMSR-E calibrated brightness temperatures (TBs) are mapped to the same polar stereographic projection used for SSM/I data to provide the research community consistency and continuity with the existing 28-year Nimbus 7 SMMR and DMSP SSM/I sea ice concentration products.
