Antarctic Trivariate products and data sets are derived from the U.S. National Ice Center archive data to provide an accurate, comprehensive, and easily understood characterization of analyzed sea ice conditions in the polar regions. The trivariate product characterizes ice coverage over time; in this case in half-month time blocks. The Single Year data shows conditions during the stated period for the year indicated. Compendium Year maps show a diachronic view of the sea ice for the stated half-month period in all years from 2007 to the date noted.
