Northern Hemisphere EASE-Grid 2.0 Weekly Snow Cover and Sea Ice Extent, Version 4

Metadata Updated: August 21, 2025

The main parameters for this data set are snow cover and sea ice extent; both parameters are derived from SMMR and DMSP-F8, -F11, -F13, and -F17 SSM/I and SSMIS brightness temperature data. These data are provided on the Northern Hemisphere EASE-Grid 2.0 projection and at a grid cell size of 25 x 25 km. This product is designed to provide a consistent weekly time series of snow cover from October 1966 through January 2023 and sea ice from October 1978 through January 2023.
