MEaSUREs Greenland Image Mosaics from Sentinel-1A and -1B, Version 1
Data set id:
NSIDC-0723
DOI: 10.5067/8LCCSFWL7L28
There is a more recent version of these data.
Overview
This data set, as part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, consists of 6- and 12-day 50 m resolution image mosaics of the Greenland coastline and ice sheet periphery. The mosaics are derived from C-band Synthetic Aperture Radar (C-SAR) acquired by the Copernicus Sentinel-1A and -1B imaging satellites between January 2015 and April 2017.
See Greenland Ice Mapping Project (GIMP) for related data.

Many NSIDC DAAC data sets can be accessed using the NSIDC DAAC's Data Access Tool. This tool provides the ability to search and filter data with spatial and temporal constraints using a map-based interface.Users have the option to
Below the image in this article, you will find sample code in IDL, MATLAB, and Python to read in a GeoTIFF file, extract the metadata, and create an image.
The code has been tested with the following data products:
We recommend using the Geospatial Data Abstraction Library (GDAL) to convert GeoTIFF files into a different format.
We recommend using the Geospatial Data Abstraction Library (GDAL) or a GIS to reproject geoTIFF files.
