• The U.S. AMSR-E Science Team uses the enhanced NASA Team (NT2) sea ice concentration algorithm to calculate the standard Arctic and Antarctic sea ice concentration products. The NT2 algorithm significantly reduces the problem of a low ice concentration bias associated with surface effects apparent in sea ice retrievals from areas of deep snow using the original NASA Team (NT) algorithm. This enhancement is achieved through the use of the AMSR-E 89GHz channels. The NT2 accommodates ice temperature variability through the use of radiance ratios as in the original NT algorithm and has the added advantage of providing weather-corrected sea ice concentrations through the utilization of a forward atmospheric radiative transfer model. This paper gives a brief summary of the concept of the algorithm and provides details of its implementation as part of the routine U.S. AMSR-E Science Team data product generation.
