Abstract
Recent studies have highlighted the need for high resolution rainfall measurements for a better modelling of urban and peri-urban catchments' responses. Indeed the catchments are smaller leading to shorter response time and the proportion of water immediately active is high due to increased imperviousness. A consequence is that the available resolution of 1km in space and 5 min in time, commonly provided by national weather services in Europe, does not seem sufficient (Gires et al. 2014). This issue is investigated in this paper with the help of two types of rainfall data: C-band radar data provided by Météo-France at a resolution of 1 Km in space and 5 min in time and data from a newly installed X-band radar operated by Ecole des Ponts ParisTech and providing data with a resolution of 100 m in space and 2.5 min in time.
