Knowledge about the spatial distribution of rainfall over cities is key to improving  urban  flood  forecasting  systems  and  helping  cities  become  more resilient  to  hydro-climatic  risks.  Unfortunately,  getting  accurate  rainfall measurements in cities often proves difficult. Professional weather stations are few and most of them are located in rural areas. Radar and satellites offer interesting alternatives, but their resolution is often too low for urban flood forecasting.Citizen Rain Gauge Networks:Recently,  a  growing  number  of  citizens  have  started  sharing  data  from  their personal  weather  stations  through  webplatforms  like  WOW  or  weather underground.
