Climate change is already leading to significant changes in rainfall patterns in the Mediterranean basin, and particularly in the south of France. The resilience of local population to extreme precipitation events requires investigative means of water vapor variability in the lower troposphere with high spatio-temporal resolution such as Raman lidar, associated to state-of-the-art weather models. This is the aim of the Water Vapor Lidar Network Assimilation (WaLiNeAs) research program, which was supported by France to carry out a demonstration campaign in autumn and winter 2022-2023.
