In this article, we evaluate the predictions of the French cloud‐resolving model AROME using a set of high‐resolution (5 km) simulations that focus on the well documented African Monsoon Multidisciplinary Analysis (AMMA) period of 23–28 July 2006 over a large domain (0–22°N, 15°W–20°E). The model skill is assessed against independent Global Positioning System observations of precipitable water and in terms of quantitative precipitation forecasts. As the rain‐gauge network is sparse over West Africa, the simulated precipitation fields were compared with data from satellite‐based precipitation products (TRMM‐3B42). We show that initial and boundary conditions significantly improve the AROME forecasts when the large‐scale forcing model (ARPEGE) assimilates surface‐sensitive observations from microwave remote‐sensing sensors over land surface.
