IV time series of Petermann glacier 1991-2010 generated using ERS-1, ERS-2 and Envisat data.
Ice velocity time series of the Petermann glacier in Greenland, derived from intensity-tracking of ERS-1/2 and Envisat data acquired between 16/08-1991 and 01/06-2010.
This data set is part of the ESA Greenland Ice sheet CCI project. It provides components of the ice velocity and the magnitude of the velocity.
The data is provided on a polar stereographic grid (EPSG3413: Latitude of true scale 70N, Reference Longitude 45E) with 500m grid spacing. The image pairs have a repeat cycle between 1 and 35 days.
The horizontal velocity is provided in true meters per day, towards EASTING(x) and NORTHING(y) direction of the grid, and the vertical displacement (z), derived from a digital elevation model, is also provided.
Data is provided as a single NetCDF file.
