Model Output of Active Layer Depth in the Arctic Drainage Basin, 1979-2001
Entry ID: ARCSS158

[ Update this Record ]

Summary
Abstract: Investigators applied the Frozen Ground Model to the entire Arctic Drainage Basin to create this data set of active layer depth (ALD), recorded in centimeters. This model has been shown to provide excellent results for active layer depth and soil temperatures when driven with well-known boundary conditions and forcing parameters at specific locations. The model is driven by 2-meter air ... View entire text

Project
Quality Modeled thaw depths for sporadic permafrost areas, mainly in the southern parts of the Arctic drainage domain, are spuriously high. In these regions, the permafrost is very isolated and occurs at sub-grid scales. The forcing data sets (surface air temperature, snow cover, and soil bulk density) are likely not representative of the true forcing conditions for these small areas and produce an unrealistic increase in thaw depth with time. Frozen ground depths of small non-permafrost areas within discontinuous permafrost are likely too high, as forcing parameters are more representative of the colder permafrost climate condition at these grid cells. ERA-40 2-meter air temperatures are used. There is no topographical correction.
