Sea Ice Concentration NSIDC Near-Real-Time Climate Data Record, Antarctic

Summary

This is 25-km sea ice concentration data for the Antarctic from the Near Real-Time NOAA/NSIDC Climate Data Record. Daily and monthly versions are available with data from the past two years. The NRT CDR fills the temporal gap between annual updates of the final CDR and provides the most recent data.

Dataset Description

This data set provides a Climate Data Record (CDR) of sea ice concentration from passive microwave data. It provides a consistent, daily and monthly time series of sea ice concentrations from 09 July 1987 through the most recent processing for both the north and south polar regions. In addition, three other sea ice concentration products are included with the CDR that extend the sea ice measurements back to 26 October 1978. However, these three products are not included in the official CDR because processing the older data in a way that follows the standards of a CDR is not currently possible. All data are on a 25 km x 25 km grid. Variables containing standard deviation, quality flags, and projection information are also included.
