DOWNLOADING DATA VIA FTP
Data can be downloaded through a Web browser or command line via FTP. When using a Web browser, the FTP link first directs you to an Optional Registration Form that if filled out, will allow you to receive notifications about updates or processing changes related to that specific data set. After completing the Optional Registration Form, the FTP directory becomes available. For additional help downloading data through an FTP client, go to the How to access data using an FTP client support page.
NOTE: Reverb will be decommissioned in the coming months and replaced with Earthdata Search. All links to Reverb will be removed at that time.
MEaSUREs Greenland Ice Sheet Velocity Map from InSAR Data, Version 2
This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, contains seasonal (winter) ice-sheet-wide velocity maps for Greenland derived from Interferometric Synthetic Aperture Radar (InSAR) data obtained by RADARSAT-1, the Advanced Land Observation Satellite (ALOS), and the TerraSAR-X satellite.
For more information, see Greenland Ice Sheet Mapping Project (GIMP).
Note: These data are considered provisional pending a review by the MEaSUREs program. Once the data have been reviewed, this statement will be removed.
For Version 2, all velocity maps underwent additional screening for quality control and bad data points were removed. In addition:
- Improved baseline fits enhance consistency in the interior;
- Updated error estimates better represent the average behavior of the data;
- ALOS fine-beam data have been added to improve coverage;
- A new velocity map is included for 2009/2010
