SPATIAL VARIABILITY OF MODEL CHARACTERISTICS OF PERMAFROST SOILS

E. K. Molkentin, E. D. Nadezhina, and O. B. Shklyarevich

Some results connected with a specific application of a numerical model for estimating a spatial distribution of permafrost parameters are analyzed. Seasonal thawing depth and temperature fields at different levels are assessed for the conditions of current climate and its future warming caused by the CO2 doubling. A Circumpolar Active-Layer Permafrost System (CAPS) containing all available data on monitoring, including those of the Russian scientists, are used to compare the results obtained with the natural characteristics.
