One-year records from automatic snow stations in western Dronning Maud Land, Antarctica
Abstract Two automatic snow stations were deployed for one year (from December 2009–January 2011) in western Dronning Maud Land. The purposes of the experiment were: 1) to build a working snow station to measure the snow surface layer temperature, and 2) to use the data for snow heat and mass balanc...
