New Version Available for MEaSUREs InSAR-Based Antarctica Ice Velocity Map
Version 2 of the MEaSUREs InSAR-Based
Antarctica Ice Velocity Map is available at the NASA
National Snow and Ice Data Center
Distributed Active Archive Center (NSIDC DAAC). Major updates to the
data set include data from 2011-2016 acquired from RADARSAT-2,
TerraSAR-X, and TanDEM-X. Landsat-8 optical imagery also was
the data to improve coverage. The mosaicking method was updated
to make best use
of the large number of scenes used for the mosaic. In addition,
parameters are included for assessing the quality of the data:
deviation of vx and vy for each pixel and count of scenes used
for each pixel.
Coverage increased from 95.1% to 99.6% and a reduction in error
due to the utilization of more data.
