Abstract:
Based on the map of landscapes and permafrost conditions in Yakutia (Merzlotno-landshaftnaya karta Yakutskoi0 ASSR, Gosgeodeziya SSSR, 1991), rasterized maps of permafrost temperature and active-layer thickness of Yakutia, East Siberia were derived. The mean and standard deviation at 0.5-degree grid cell size are estimated by assigning a probability density function at 0.001-degree spatial resolution. Spatial pattern of both variables are dominated by a climatic gradient from north to south, and by mountains and the soil type distribution. Uncertainties are highest in mountains and in the sporadic permafrost zone in the south. The maps are best suited as a benchmark for land surface models which include a permafrost module.

Comment:
The map of subsoil temperature of Yakutian ASSR is based on the map 'Merzlonto-landschaftnaya karta Yakutskoi ASSR, Gosgeodeziya SSSR, 1991'. The original Russian map has been digitized into several GIS layers, scale 1: 2 500 000. Based on this digitized version fine scale raster images have been produced which were the basis for a proper scaling to 0.5 degree including uncertainty. For most of the landscapes the subsoil temperature represents permafrost temperature. For regions with isolated patches of permafrost it represents the average of permafrost temperature and non-permafrost subsoil temperature. The data represent the period 1960-1987.
