Data Set ID:

DMSP-F8 SSM/I Pathfinder Global Level 2 Sea Ice Concentrations, Version 1

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.
