Project Summary

At present, rapidly changing atmospheric conditions in the Arctic induce an acceleration of Arctic land-ice mass loss, yielding a significant contribution to sea level rise (30% since the 1990s). This highlights the need for close collaboration between glaciologists and atmospheric scientists, which is key to better understand the role of the glaciers, ice caps and the Greenland Ice Sheet in the Arctic climate system and ultimately reduce uncertainties in future climate and sea level projections.

We propose a cross-cutting activity on glacier-atmosphere interactions, focusing on three main topics:

  1. Atmospheric circulation patterns and the impact on the Arctic land-ice mass budget
  2. Precipitation and snowfall in the Arctic – observations & modelling
  3. Coupling of glaciers and atmosphere in general circulation models (GCMs), regional climate models (RCMs) and earth system models (ESMs)

The activity will be implemented in the next annual meeting of the IASC Network on Arctic Glaciology (NAG; and workshop on the Dynamics and Mass Budget of Arctic Glaciers, to be held in Obergurgl, Austria, 26-28 January 2023. The cross-cutting activity will be in the form of presentation and discussion sessions.
