The Climate and Land-Surface Systems Interaction Centre (CLASSIC) is a NERC Collaborative Centre funded under the Earth Observation Centres of Excellence programme.

Hosted at Swansea University, CLASSIC brings together a consortium of researchers from the NERC Centre for Ecology and Hydrology at Wallingford and Monks Wood, the University of Durham, and the Hadley Centre for Climate Prediction and Research.

The principal goal of CLASSIC is to reduce uncertainty in assessing the actual and potential effects of climate change through an improved understanding of the feedback mechanisms that exist between the land surface and the atmosphere. This will be achieved through the development of improved Land-Surface Schemes and Dynamic Vegetation Models, within both Global and Regional Climate Models, that fully reproduce these interactions and that can be driven by dynamic, spatially comprehensive data on the terrestrial biosphere, such as those provided from Earth Observation.
