For several summers this deeply incised melt channel transported overflow from a large melt lake to a Moulin (a conduit drains the water through many hundreds of feet to the ice sheet’s bed). (note people near left edge for scale).

Welcome! We are the Ice Sheets and Climate research group, led by Jan Lenaerts. We are part of the Department of Atmospheric and Oceanic Sciences (ATOC).

In our group, we try to understand and answer the following scientific questions:

How do ice sheets respond to climate and climate change? 

What are the main processes driving this ice sheet response?

How can we improve the models that represent these processes?

Our research focuses on the interaction between the ice and snow in the polar regions and the remainder of the global climate system. We are interested in the processes that drive this change, especially in the atmosphere (large-scale atmospheric circulation, atmospheric warming), but also in the snow and ice (surface melt, runoff) and especially these processes that are a combination of the two (albedo-melt feedback, drifting snow, polar clouds, etc.). Our main tools are climate models, which we try to understand & improve by combining observations (in-situ, remote sensing) with knowledge on the physical processes. 

Our group is strongly involved in the Community Earth System Model (CESM) consortium. As members of the Land Ice Working Group, we aim to understand ice sheet changes in a global context. 

Group news

We are currently recruiting one graduate student interested in regional-scale atmospheric-snow processes (starting ~Spring/Summer 2018), and willing to go into the East Antarctic field! If you are interested in this position, or any other possibility in joining our team, please do not hesitate to contact Jan Lenaerts.
