SM2RAIN algorithm is very recent and provides an estimation of the accumulated rainfall. First promising studies highlight the capability to provide long-term rainfall dataset for climate applications (Abera, Brocca, L., et al. HESS) Exploitation of new satellite soil moisture missions (SMAP, SMOS, Sentinel-1) River discharge and lake volume are usually obtained from in situ gauged station but recently the monitoring network is declining. A completely innovative approach to provide a long term dataset useful for climate and long period studies on river discharge and water volume variation of lakes through the optimal exploitation and integration of multi-mission products.

11 BENEFITS FOR ITALY 1. Interest for the hydrological community to use satellite sensors for ungauged sites for estimating long time series and derive climatic trends, for Lakes (a CCI+ ECV), River Discharge (to be proposed by ASI to ESA CCI+ on behalf of IRPI). IRPI can be the prime contractor, leading an international team to tackle climatic trends in river discharge worldwide. 2. Use of the developed products for natural disaster monitoring and management (the responsible authorities, Civil protection and regional authorities have already manifested their interest). The soil moisture based rainfall estimates have proved to be particularly useful for improving floods and landslides prediction. 3. Increased importance of the role of Italy in similar projects (H-SAF, SAF for hydrology from EUMETSAT, ESA STSE, SEOM) through the experience developed with the CCI+ teams. 4. New contribution to CCI+ from Italy which could open new collaborations and attract funds from other related projects. 5. Italian labs increased skills to boost their international recognition in order to increase fund attractivity (e.g. H2020). ACKNOWLEDGEMENT: Jérôme Benveniste Senior Advisor, ESA/ESRIN
