UCL's Polar Science Group is a founding member of the UK's NERC Center for Polar Observation and Modelling (CPOM).
CPOM, which is now part of the British Antarctic Survey (BAS), originated at UCL in 2000 and comprises
leading polar science groups from the universities of Leeds, Reading, Bristol, Lancaster, Swansea, Exeter and UCL, collaborating on UK national programmes of
polar science research.
Scientists from UCL's Polar Science Group currently also lead a number of major international cryosphere research projects from the European Space Agency (ESA) and other agencies.

Our group is at the interface between remote sensing, field and laboratory work and climate modelling.
We build on our pioneering work on satellite altimetry of the polar regions with the launch in 2010 of CryoSat-2 to develop a
wide suit of remote sensing techniques to investigate changes in the cryosphere and polar oceans.
We have developed several sea ice model parameterizations that have now been incorporated in a variety of Global Circulation Models (i.e. Met Office) and assimilate our satellite observation into operational forecasting systems. We are leading regular field work campaigns (i.e. MOSAiC Arctic expedition) and develop new instruments to probe in-situ characteristics of the snow and sea ice and validate models and satellite data.
Finally, we are performing laboratory experiments in polar conditions in our cold room facility in the Department of Earth Sciences.
