The objective of this study is to evaluate satellite rainfall products' ability to estimate river runoff over 12 basins in Morocco using four hydrological models: IHACRES, MISDc, GR4J, and CREST. Satellite products available with a short latency are compared: EUMETSAT H SAF, SM2RAIN-ASCAT, and IMERG. The best results to reproduce river runoff were obtained with SM2RAIN-ASCAT in combination with the IHACRES model, with the highest Kling-Gupta efficiency criterion and probability of detection of extreme runoff. The hydrological model performances differed across catchments and satellite rainfall products, which highlights the need to carefully select hydrological models for a given application. Thus, it is advisable to evaluate satellite rainfall products with different types of hydrological models. This first evaluation over Moroccan basins suggests that SM2RAIN-ASCAT could be a reliable alternative to observed rainfall for hydrological modelling. specialized satellite rainfall Morocco SM2RAIN hydrological models MAROC 062 020 126 68 3 474-487 2023 0262-6667 https://www.documentation.ird.fr/hor/fdi:010086985 10.1080/02626667.2023.2171295 0262-6667 [F B010086985] https://www.documentation.ird.fr/hor/fdi:010086985 https://www.documentation.ird.fr/intranet/publi/2023-04/010086985.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2023-04-14 2025-02-24 fdi:010086985 fre
