Dr. David Schroeder

Senior Sea Ice Model Development Scientist

Centre for Polar Observation and Modelling

My role, as a National Capability scientist, is to improve the climate sea ice model CICE by implementing new physics and to support and guide researchers at the University of Reading and along the wider UK Polar Research Community. This includes applying CICE in stand-alone mode as well as part of a Global Climate Model and providing technical and scientific support as well as exchanging experience and expertise about suitable model configurations. I have strong collaborations with the Met Office, National Oceanography Centre in Southampton (NOCS), the British Antarctic Survey (BAS) and the Los Alamos National Laboratory in the USA. I am part of the NERC Long Term Science Multi-centre Projects UKESM (The UK Earth system modelling project) and ACSIS (North Atlantic Climate System Integrated Study).
