Abstract
The Royal Society of Canada coordinates the International Geosphere‐Biosphere Program (Global Change) in Canada. Currently, a research agenda that will extend beyond the next decade is being developed. It includes the use of remote sensing and geographical information systems in support of Global Change research, and the study of issues related to change and variability in the Canadian Arctic.This paper reviews the use of remotely sensed data to study the nature of atmosphere‐cryosphere interactions in the Polar Basin and how they contribute to an understanding of climate change and variability. A conceptual framework for aspects of atmosphere‐cryosphere interaction is presented through a discussion of feedback scenarios. The role of remote sensing in understanding these scenarios is explored through an examination of the several studies over the past 15 years. Finally, the remote sensing capabilities for crysophere monitoring proposed for the satellite systems of the mid‐1990s will be discussed.
