Northern Hemisphere EASE-Grid 2.0 Weekly Snow Cover and Sea Ice Extent, Version 4
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/p7o0hgjlyuqu
The main parameters for this data set are snow cover and sea ice extent, provided on the Northern Hemisphere EASE-Grid 2.0 projection at a grid cell size of 25 x 25 km.
Description
Snow cover extent is based on the NOAA/NCDC Climate Data Record (CDR) of Northern Hemisphere (NH) Snow Cover Extent (SCE) by D. Robinson (2012) and regridded to the EASE-Grid. The NOAA/NCDC CDR of Northern Hemisphere Snow Cover Extent data were derived from the manual interpretation of AVHRR, GOES, and other visible-band satellite data (Helfrich et al. 2007).
Sea ice extent is derived from Sea Ice Concentrations from Nimbus-7 SMMR and DMSP SSM/I-SSMIS Passive Microwave Data (NSIDC-0051) and regridded to the EASE-Grid. 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.
