AB: This study examines the spatial and temporal variability of supraglacial melt lakes over the western ablation zone of the Greenland ice sheet. Based on mid-lake automatic weather station surface energy budget measurements, automatic camera imagery, and inflatable boat measurements, we derive lake volume estimates from daily 250 m MODIS imagery for this region. We investigate the correlation of the timing and location of lake water volume and correlation with local-scale climate anomalies from Polar MM5 regional climate model output. Implications for water supply to melt-induced ice sheet acceleration are discussed.
