This data set contains modeled active-layer depth (cm) from 50 deg N to 80 deg N, and 60 deg E to 160 deg E, Russia. Depth values are calculated from a model of current climate that assumes a complex surface with inhomogenous vegetation and soil texture, and from a model of projected climate for the year 2050 that assumes uniform vegetation and soil. Tab-delimited ASCII text files contain active-layer depth values (cm) with corresponding latitudes and longitudes in decimal degrees. Maps of active-layer depth (cm) are in GIF image format. Data are available via FTP.
