MEaSUREs Greenland Ice Sheet Mosaics from SAR Data, Version 1
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/6187dqul3fr5
This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, contains high resolution mosaics of radar backscatter for the Greenland Ice Sheet derived from synthetic aperture radar (SAR) data.
Description
Both calibrated and uncalibrated mosaics are available for: the winters of 2000-2001, 2005-2006 through 2008-2009, and 2012-2013; and a multiyear composite. Uncalibrated mosaics are available for the winter of 2009-2010.
All mosaics are provided at both 100 m and 20 m resolutions. See Greenland Ice Sheet Mapping Project at nsidc.org/grimp for related data.
