Satellite Calibration And Validation Experiments Over Arctic Sea Ice In The Vicinity Of Svalbard
Abstract
In late summer 2010, in situ observations on Arctic sea ice were performed at the end of the melting season north of Svalbard, and in the Fram Strait. High resolution Radarsat-2 SAR images were obtained. Simultaneously, data about sea ice and snow thickness, ice topography, and melt ponds was collected. A helicopter performed ice thickness surveys using an electromagnetic (EM) device, accompanied with automatic photography and laser altimetry. The EM method is also used for the calibration and validation of data from the new CryoSat-2 radar altimetry satellite. Data on snow and ice properties have been collected over several years for satellite altimetry calibration. These are necessary for estimating the sea ice thickness from measured freeboard. Preliminary results indicate the improved possibilities for ice type classification from SAR satellite imagery. Data collected for CryoSat- 2 calibration and validation will contribute to improve data quality of CryoSat-2 products.
