   Description: 
      Abstract:
         The Northern Hemisphere EASE-Grid 2.0 Weekly Snow Cover and Sea Ice Extent 
         Version 4 product combine snow cover and sea ice extent at weekly intervals 
         from 23 October 1978 through 29 June 2014, and snow cover alone from 03 
         October 1966 through 29 June 2014. Snow cover extent for this data set 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 regridded to 
         EASE-Grid from Sea Ice Concentrations from Nimbus-7 SMMR and DMSP SSM/I-SSMIS 
         Passive Microwave Data. Designed to facilitate study of Northern Hemisphere 
         seasonal fluctuations of snow cover and sea ice extent, the data set also 
         includes monthly climatologies describing average extent, probability of 
         occurrence, and variance. Data are provided in flat, unsigned binary files and 
         are available via FTP.
