Abrupt increases in soil temperatures following increased precipitation in a permafrost region, central Lena River basin, Russia
Marked increases in active‐layer and upper permafrost temperatures occurred in the central Lena River basin in association with abrupt increases in active‐layer soil moisture following the summer of 2005. The positive trend in soil temperature‐moisture relations was observed at monitoring sites in t...
