NSIDC DAAC Updates the Near-Real-Time SSM/I-SSMIS EASE-Grid Daily Global Ice Concentration and Snow Extent Data Set

The Near-Real-Time SSM/I-SSMIS EASE-Grid Daily Global Ice Concentration and Snow Extent data set, available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) has been updated to Version 5. The NISE Version 5 data record begins 12/01/2016. A two-month overlap with NISE Version 4 is planned: 12/01/2016-01/31/2017.

The following changes were also made to this version of data:

  • The NISE snow and sea ice algorithm both use near-real-time brightness temperature observations from the SSMIS instrument on DMSP-F18.
  • The coefficients for the NISE snow algorithm were updated to better match results from DMSP-F13 as a result of an inter-calibration between F13 and F17 during an overlap period from 3/27/2008-3/26/2009 and between F17 and F18 during an overlap period from 7/1/2014-6/30/2015.
  • ESDT metadata was updated to reflect the change in data set version number.
