Abstract: Real-time monitoring snowfall events in Po valley is often difficult due to fast temperature variations that change snow / rain limits. For this reason Arpa Lombardia is developing a network of volunteers and automatic weather sensors coupled with radar-based precipitation type products. Five automatic present weather sensors FD12P have been recently installed; they are able to discriminated solid and liquid precipitation combining temperature, humidity and optical measurements. An algorithm to discriminate the phase of precipitation at ground level, which involves radar and local area model data, has been developed several years ago by Arpa Piemonte. Wet bulb temperature derived from the nonhydrostatic limited-area atmospheric model COSMO and best precipitation estimations from polarimentric radar are ingredients of the precipitation type algorithm. Finally a dense network of specialized observers also provide snow depth and fresh snow measurements that are used both to improve monitoring of areas interested by snowfall and automatic algorithm to assess precipitation type. The present work describe the monitoring system set up in Lombardia to monitor snowfall and it shows results from heavy snowfall event occurred during winter season 2012 / 2013.
