Antarctic Daily Sea Ice Concentration Gridded Level 3 Composite from SSM/I onboard DMSP

This level 3 product contains daily sea ice concentration from the 85 GHz channel of SSM/I on DMSP over Antarctic on polar sterographic 12.5 km resolution grids, available since 1992. The maps are processed from the daily brightness temperature maps from NSIDC. The Artist Sea Ice (ASI) algorithm developped at University of Bremen (Germany) is used to processed daily sea ice concentration maps at 12.5 km resolution. The dataset covers the whole 85 GHz SSM/I mission. We are grateful to NSIDC (Boulder, Colorado) for the SSMI data.

This dataset is also available over Arctic.
