Overview

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.

FAQs About NSIDC DAAC's Earthdata Cloud Migration

This article covers frequently asked questions about the NASA NSIDC DAAC's Earthdata cloud migration project and what it means to data users.

The NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) is migrating its primary data access from its legacy, on-premises archive to the NASA Earthdata Cloud.

How to Articles

Downloading Data from Earthdata Cloud to Your Local Computer Using the Command Line

This article shows how to download NSIDC DAAC data from NASA Earthdata Cloud to your computer using three tools: wget and curl—popular command-line utilities for downloading files—and Data Downloader, a Python-based command-line tool developed by the Physical Oceanography Distributed Active Archi

How can I use code to read GeoTiffs?

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.

There are external Jupyter notebooks available that can be used to search for GrIMP products and incorporate them into a new QGIS project:
