Radar altimeter sea ice model

Simulations, using the new radar altimeter sea ice model, show that the Ku-band effective scattering surface depth is sensitive to snow density, thickness and the snow and ice surface roughness. In order to reduce errors in sea ice freeboard estimation and the derived ice thickness to acceptable levels it will be necessary to have access to these snow and ice parameters. The result is significant for the systematic mapping of sea ice thickness and the upcoming European ESA CRYOSAT mission, where part of the objective is to measure sea ice freeboard and thickness.
