TB's are gridded into 12.5 km grid cells using a drop-in-the-bucket method where the grid cell that contains the center of the observation footprint is given the whole weight of the observation. NT2 sea ice concentrations are calculated using the individual Level-2A TB's in order to make the atmospheric corrections on an orbit-by-orbit basis before obtaining daily average ice concentrations. Snow depth over sea ice is a 5-day running average, which is based on the current day and the previous four days. Sea ice concentration and brightness temperatures include daily ascending averages, daily descending averages, and daily averages; snow depth over sea ice is a five-day running average. The AMSR-E/Aqua Level-2A swath product includes brightness temperatures at 6.9 GHz, 10.7 GHz, 18.7 GHz, 23.8 GHz, 36.5 GHz, and 89.0 GHz resampled at resolutions of 56 km, 38 km, 21 km, 12 km, and 5.4 km.

The primary source of error is attributed to conditions in the surface layer such as surface glaze and layering, which can significantly affect the horizontally polarized 18.7 GHz TB, leading to an underestimation of sea ice concentration. The NT2 algorithm uses the 89 GHz channels because the horizontally polarized 89 GHz data are less affected by surface conditions than the horizontally polarized 18.7 GHz data, and the 89 GHz channels have successfully been used in sea ice concentration retrievals under clear atmospheric conditions. As a result, this algorithm can identify more complex ice types resulting from surface glaze and layering in the snow cover. The thin-ice bias is then reduced. Bootstrap Basic Algorithm (BBA) 2013-11-12 lastUpdate 20131112 Josefino Comiso NASA / GSFC Cryospheric Sciences Laboratory josefino.c.comiso@nasa.gov author The Bootstrap Basic Algorithm (BBA) uses two sets of channels to identify consolidated ice and open water: 18.7V GHz and 37V GHz, and 37H GHz and 37V GHz. Using these channels for the retrieval of sea ice concentration ensures consistency with historical sea ice products, beginning with SMMR. Snow Depth on Sea Ice 2013-11-12 lastUpdate 20131112 Dr. Thorsten Markus NASA / GSFC Cryospheric Sciences Laboratory thorsten.markus@nasa.gov author Dr. Donald Cavalieri NASA / GSFC Cryospheric Sciences Laboratory donald.j.cavalieri@nasa.gov author Snow depth on sea ice is a 5-day running average of the current day and the previous four days. This algorithm is only valid over seasonal ice. The snow depth on sea ice is calculated using a spectral gradient ratio of the 18.7 GHz and 36.5 GHz vertical polarization channels. The algorithm uses 2 masks: a multiyear sea ice mask updated daily by the NT2 algorithm and a running 5-day snow melt mask corresponding to the snow depth on ice product. The AMSR-E/Aqua Level 3 12.5 km daily sea ice product includes 18.7 - 89.0 GHz TBs, sea ice concentration averages, and 5-day snow depth over sea ice on a 12.5 km polar stereographic grid, generated by the NT2 algorithm using Level-2A TBs. This validated version includes an updated Southern Hemisphere sea ice mask derived from National Ice Center data (June 2011) and updated flags correlating with the new mask.
