Fine spatialization of climate projections in the Tleta watershed in northern Morocco

Abstract

Local studies of climate change impact require high spatial resolution of climate predictions. Within ALMIRA research project, agronomists and hydrologists wish to integrate climate predictions into their models in order to characterize the behavior of Tleta watershed by 2050. Global and regional climate models can only apprehend it through one or fewer pixels at best. It is also essential to use a statistical downscaling method, which allows for improving spatial resolution. Based on climate predictions from the French ALADIN-Climate model and available climatic series, a processing sequence has been developed to provide spatialized fields of climatic variables over the period 2021-2060 at 1 km² resolution.
