Katabatic winds and piteraq storms: observations from the Greenland ice sheet

摘要

In 2007 the Programme for Monitoring the Greenland IceSheet (PROMICE) was initiated to observe and gain insightinto the mass budget of Greenland ice masses. By means ofin situ observations and remote sensing, PROMICE assesseshow much mass is gained as snow accumulation on the surface versus how much is lost by iceberg calving and surfaceablation (Ahlstr?m et al. 2008). A key element of PROMICE is a network of automatic weather stations (AWSs) designed to quantify components of the surface mass balance,including the energy exchanges contributing to surface ablation (Van As et al. 2013).
