Climate change scenarios at hourly time‐step over Switzerland from an enhanced temporal downscaling approach

Michael Lehning, Wolf Hendrik Huwald, Varun Sharma, Adrien Michel

Many physically‐based models for climate change impact studies require sub‐daily temporal resolution of the forcing data to provide meaningful predictions. However, climate scenarios are typically available at daily time step, severely limiting the applica ...
