Sea Ice Trends and Climatologies from SMMR and SSM/I  View Catalog Page Entry ID
NSIDC-0192
Summary
NSIDC provides a suite of value-added products to aid in investigations of the variability and trends of sea ice cover. These products provide users with information about sea ice extent, total ice-covered area, ice persistence, monthly climatologies of sea ice concentrations, and ocean masks. The maps are in ArcInfo export file format. All other products are in flat binary or ASCII format with accompanying Portable Network Graphics (PNG) browse images. Products are derived from Nimbus-7 SMMR and DMSP-F8, -F11, and -F13 SSM/I sea ice concentrations at a grid cell size of 25 x 25 km. Data begin in October 1978 and processing is ongoing. Data are available via FTP.

Quality
Please note that these products may not contain the most recent data; therefore, you should use caution, particularly with the ocean masks and sea ice climatologies, which may not be representative of ice cover conditions outside of the time period used to produce the products.
