Characterization of Freeze-Thaw Process Heterogeneity with Spaceborne Radar
The landmass of the boreal high latitudes encompasses almost 30 percent of the global land area. Within these regions, a major portion of the Earth’s carbon is stored in vegetation and in seasonally frozen and permafrost soils.
Assessing the Potential for Wildfire Using ERS-2 SAR Imagery
Wildfire is a common occurrence in boreal Alaska and natural resource agencies devote considerable resources to fire management and suppression. Currently, these agencies rely on the Canadian Forest Fire Danger Rating System’s Fire Weather Index (FWI) for the assessment of the potential for wildfire. FWI is based solely on point-source weather data collected daily in a sparse network across the state of Alaska.
Use of SAR to Improve Paleo-Climate Investigations at Lake El’gygytgyn, Siberia
A time-series of more than 450 combined ERS-2, RADARSAT-1, and Landsat-7 scenes acquired between 1998 and 2001 was analyzed to develop a fairly complete picture of lake ice dynamics on arctic Lake El’gygytgyn, NE Siberia (67.5°N, 172°E).
