The surface energy balance of a polygonal tundra site in northern Siberia – Part 1: Spring to fall. (PANGAEA, 2012-09-26)In this article, we present a study on the surface energy balance of a polygonal tundra landscape in northeast Siberia. The study was performed during half-year periods from April to September in each of 2007 and 2008. The ...
