Atmosphere-Ocean General Circulation Models (AOGCMs) operate on a coarse spatial scale of hundreds of kilometres. Whilst these climate models have demonstrated skill in reproducing observed features on hemispherical and continental scales their outputs are not intended for direct use on regional or local scales, i.e., the scale most pertinent for climate change adaptation and impact work. In this session we invite contributions on new and established downscaling techniques and their applications. This includes dynamical and statistical approaches. Contributions can include both theoretical advances in downscaling as well as applications of downscaled climate data in the environmental field.
