DMSP-F8 SSM/I Pathfinder Global Level 2 Sea Ice ConcentrationsEntry ID: NSIDC-0028
Abstract: These sea ice concentrations have been generated by applying the NASA Team algorithm to DMSP F8 SSM/I brightness temperature observations from 19 GHz (vertical and horizontal), 37- and 22 GHz vertical frequencies, calculating two gradients for use as weather filters. Global coverage is provided, but sea ice concentrations are only derived for ocean, ice, and possible ice surfaces poleward of 35 degrees latitude, from 1 August 1987 through 30 November 1988. In the Northern Hemisphere, where data are not filtered due to weather effects, first-year and multi-year concentrations (in percent) are calculated; total ice concentration is taken as the sum of these two. Only total ice is calculated for the Southern Hemisphere. 25 km swath data are in HDF, available via FTP.
