Northern Hemisphere EASE-Grid 2.0 Weekly Snow Cover and Sea Ice Extent
Entry ID: NSIDC-0046

Abstract: This data set is generated from brightness temperature data derived from the following sensors: SMMR, DMSP -F8, -F11 and -F13, SSM/Is, and SSMIS. The data are provided in the polar stereographic projection at a grid cell size of 25 x 25 km. This product is designed to provide a consistent time series of sea ice concentrations, the fraction or percentage of ocean area covered by sea ice, spanning the coverage of several passive microwave instruments.
