| Summary: | A simple surface climate simulator has the capacity to model the thermal con-trast produced by stratification, variable sea ice or active layer thickness and albedo in the environment of the Alaskan North Slope. These simulations form the background for modeling the probable ffects of terrain modifications pro-duced by Arctic construction. This strategy should allow investigators to estimate the most appropriate times for the discrimination of specific targets using ther-mal imagery as a prospecting medium and facilitate the interpretation f existing imagery. Lastly, the scheme allows investigators of surface modification effects to setect probable subsets of processes for field evaluation by examining the sensitivity of the thermal response to variations of the input properties over their anticipated ranges in conjunction with estimates of the local meteorological environment. This sequence can also be used to test the physical validity of process arguments used in the interpretation of thermal contrast in recon-naissance imagery. |
