Using the NASA scatterometer (NSCAT), the temporal change in the radar backscatter signature across Alaska was monitored to assess the scatterometer's capability for monitoring freeze/thaw transitions in northern ecotones. NSCAT flew from September 1996 through June 1997, providing approximately 9 months of high-quality data. Data from the ground stations was used to quantify the backscatter sensitivity to landscape freeze/thaw state under a variety of terrain and landcover conditions. Overall, the results confirm the potential of the scatterometer for measuring the timing of surface freeze-thaw transitions and associated shifts in hydrologic activity.
