IV time series of the Zachariae and 79Fjord area 1991-2011 generated using ERS-1+2 and Envisat data.
Ice velocity time series of the Zachariae and 79Fjord area in Greenland, derived from intensity-tracking of ERS-1/2 and Envisat data acquired between 01/08-1991 and 07/02/2011.
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.
