• Due to planned system maintenance taking place on Wednesday, October 5 from 10 - 11 a.m. (USA Mountain Time), data set landing pages and other related data pages may be temporarily unavailable or behave unexpectedly during that timeframe.

  • On Wednesday, October 5, from 9 a.m. to 12 p.m. (Mountain Time), the following data collections may not be available due to planned system maintenance: AMSR Unified, AMSR-E, Aquarius, High Mountain Asia, IceBridge, ICESat/GLAS, ICESat-2, LVIS, MEaSUREs, MODIS, SMAP, SnowEx, SSM/I-SSMIS and VIIRS.

MEaSUREs Greenland Monthly Ice Sheet Velocity Mosaics from SAR and Landsat, Version 4 (NSIDC-0731)
Data set:
This is the most recent version of these data.
Version Summary
Changes for the version include:
- Temporal coverage extended
- Data recalibrated relative to previous versions to reduces biases imposed by quadratic fits to control points
- Correction added for the submergence/emergence velocity
- Addition of interferometric phase data where available


This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, contains monthly ice velocity mosaics for the Greenland Ice Sheet derived from Synthetic Aperture Radar (SAR) data obtained by the German Aerospace Center's (DLR) TerraSAR-X/TanDEM-X (TSX/TDX), the European Space Agency's (ESA) Copernicus Sentinel-1A and -1B satellites, and from US Geological Survey (USGS) Landsat 8 optical imagery. See Greenland Ice Mapping Project (GrIMP) for related data.

How To

The answer is yes. 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 data from:
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.
There are external Jupyter notebooks available that can be used to search for GIMP products and incorporate them into a new QGIS project:
All data from the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) can be accessed directly from our HTTPS file system, using wget or curl. Basic command line instructions are provided in the article below.
