Geocoding and projection info:
The backscatter data were transformed to map coordinates using the GLAS/ICESat 1 km 
Laser Altimetry Digital Elevation Model of Greenland which is provided at Polar 
Stereographic grids (DiMarzio, J., Brenner, A., Schutz, R., Schuman, A. & Zwally, H.J. 
(2007): GLAS/ICESat 1 km laser altimetri digital elevation model of Greenland. Boulder, 
Colorado USA: National Snow and Ice Data Centre. Digital media).

Temporal coverage:
The dataset consists of 38 synthetic aperture radar (SAR) backscatter images acquired 
every 3 days between the 12th March and 1st July 2011 during the ERS-2 3-day campaign. 


File naming convention:
20110312.tif                -  SAR backscatter intensity images
The name of the velocity files provides the date of the acquisition.
