Surface meltwater production timeseries for Sermeq Avannarleq, western Greenland Ice Sheet from 2017-2018.
We calculate surface meltwater production (hourly melt rates) for three on-ice weather stations located in the ablation area of Sermeq Avannarleq, an outlet glacier of the western Greenland Ice Sheet. We use data from two automatic weather stations (AWS) installed during the MoVE project (Moulin and...
