Instantaneous daytime conductive heat flow through snow on lake ice in Alaska
Abstract The instantaneous daytime conductive heat flow through the snow on lake ice was derived from snow depth, temperature and density measurements made during the course of six winters at MST Pond in central Alaska. The MST Pond data for winter 2003–04 are compared with results for the same peri...
