DOI: 10.1002/2017gl073661
Abstract: Abstract Calibration and validation of satellite-derived ice sheet albedo data require high-quality, in-situ measurements commonly acquired by up- and down-facing pyranometers mounted on automated weather stations (AWS). However, direct comparison between ground and satellite-derived albedo… read more here.

DOI: 10.1002/2017gl075958
Abstract: Surface ablation of the Greenland ice sheet is amplified by surface darkening caused by light-absorbing impurities such as mineral dust, black carbon, and pigmented microbial cells. We present the first quantitative assessment of the microbial… read more here.
