A Comprehensive Ice Velocity Map of Greenland from RADARSAT-1 and Other Satellite Data
The rate at which Greenland discharges ice to the ocean has accelerated dramatically over the last several years. These changes are significant and likely indicate a response to climate change (e.g., enhanced basal lubrication from surface melt draining to the bed or dynamic response due to the loss of resistance from grounded and floating ice as calving fronts retreat).
ASF Provides Open Source Software for Increasing the Usability of SAR Data
Synthetic Aperture Radar (SAR) technology has been around for quite some time now, but only in recent years has it become a common data type. The long path to popularity can most likely be attributed to a couple characteristics associated with SAR data. First, SAR data are typically provided in one of several CEOS formats.
