Description :

IV time series of Hagen glacier 1991-2010 generated using ERS-1, ERS-2 and Envisat data.

Comments :

Ice velocity time series of the Hagen glacier in Greenland, derived from intensity-tracking of ERS-1/2 and Envisat data acquired between 26/08-1991 and 07/05-2010.

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 are provided on a polar stereographic grid (EPSG3413: Latitude of true scale 70N, Reference Longitude 45E) with 500m grid spacing. Image pairs with a repeat cycle of 6 to 35 days are used.

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.
