The Centre for Polar Observation and Modelling (CPOM) is a research centre that studies processes in the Earth's polar latitudes that may affect the Earth's albedo, polar atmosphere and ocean circulation, and global sea level. We use theoretical and laboratory-derived understanding to form new mesoscale models of interactions between the ice, ocean and atmosphere, and use ground and satellite observations to test the predictions of these and other climate models. CPOM is funded by the Natural Environment Research Council and is part of the National Centre for Earth Observation. It has research groups in the Department of Earth Sciences at University College London, at the Bristol Glaciology Centre at the University of Bristol and in the School of Earth and Environment at the University of Leeds.
