For a study I am conducting about an urban drainage system in Campania, I need precipitation data.

I already have rain-gauge data with a temporal resolution of 10 min, downloaded from Centro Funzionale Multirischi della Protezione Civile Regione Campania.

However, I assume that rain-gauge data have a low spatial resolution when compared with radar data.

Since I am no expert in this field I was wondering if radar-data for precipitation (rainfall) is available for Campania region, and if yes, where is it possible to download the data.

Thanks in advance.
