Measuring Climatic State Variables from SAR Images of Sea Ice: The SIMS SAR Validation Site in Lancaster Sound
ABSTRACT. In this paper we consider three aspects of arctic sea ice climate studies: a review of climate processes related to a seasonal sea ice cover, a review of how climate state variables related to the reviewed processes may be measured using remote sensing data, and an analysis of the relative...
