Added value of integrated satellite precipitation products for event-based flood modeling in semi-arid regions

Mariame Rachdane, El Mahdi El Khalki, Yves Tramblay, Luca Ciabatta et autres

Accurate flood simulation and forecasting are often hindered by the limited availability of high-resolution rainfall observations, particularly at sub-daily scales. This challenge is especially pronounced in developing countries such as Morocco, where dense rain gauge networks are lacking. Satellite-based precipitation products offer …

Multiscale evaluation of gridded precipitation and temperature in the High Atlas (Morocco)

Omar Zemrani, Mohamed Elmehdi Saidi, Sara Boughdadi, Mariame Rachdane et autres

ABSTRACT This study presents a multiscale evaluation of five gridded climate products, ERA5-Land, TerraClimate, CHIRPS, CHIRTS, and PERSIANN CCS-CDR, over the semiarid topographically complex High Atlas Mountains of Morocco. Using observations from nine ground stations, performance was assessed at daily, monthly, and …
