Inter annual variability in Greenland Albedo from Satellite

Inter annual variability in Greenland Albedo from Satellite

The Greenland Ice Sheet contains enough fresh water to raise global sea level by 7.4m. Over the last two decades, the annual mass balance for Greenland has become increasingly negative, primarily as a result of an increase in surface melting. Since the surface albedo is the dominant factor governing the amount of surface ablation during summer, monitoring changes in surface albedo has thus become increasingly important.

The MODerate resolution Imaging Spectroradiometer (MODIS) satellite provides more than 18 years of daily albedo observations. This summer project aims to update previously published trends on MODIS albedo, perform some intercomparisons with station data to verify continued accuracy of the satellite-derived albedo, and test whether or not significant changes in albedo during particular time-periods may be linked to wildfires.
