We installed two weather stations during the 2017 melt season to constrain melt rates at two different elevations in the ablation area of Sermeq Avannarleq, on the western Greenland Ice Sheet. LOWC Weather station was installed at our Low Camp field site where the elevation is approximately 780 meters above sea level (m.a.s.l) and the ice is ~500 meters (m) thick. HIGH Weather station was installed at our High Camp field site where the elevation is approximately 950 m.a.s.l. and the ice is ~750m thick. Each station was equipped with a HOBO/ONSET U30 data logger set to record observations continuously every 15 minutes. Each station was mounted to 1.25-inch aluminum conduit, drilled and frozen into the ice. Instruments were mounted approximately two meters above the ice surface upon initial installation in 2017. During the 2017 melt season HIGH weather station experienced surface lowering of 50.2 centimeters (cm) from 2017-07-30 through 2017-08-15. Heavy snow fall beginning 16 Aug. 2020 effectively ended the ...
