Meteorological control on interannual spatial and temporal variations in snow cover and ground thawing in two northeast Greenlandic Circumpolar‐Active‐Layer‐Monitoring (CALM) sites
Abstract Data on snow cover depletion and ground thawing at two sites at Zackenberg, in high arctic northeast Greenland, are presented from 1996 to 2002. Operation of the two Zackenberg Ecological Research Operations (ZERO) Circumpolar‐Active‐Layer‐Monitoring (ZEROCALM) sites is part of ZERO. Year‐r...
