ACTIVITIES TO BE PROPOSED TO THE CCI+ PROGRAMME
• Long-term analysis, assessment and development of SM2RAIN-derived rainfall products starting from multiple satellite soil moisture products:
oCCI soil moistureoRecent missions (SMOS, SMAP, Sentinel-1)
• Development of long time series of lake level and surface area (essential for lake volume variation estimate), river water level and discharge through the integration of multiple sensors:
oRadar altimetryoOpticaloSAR
• Exploitation of the newly developed products for hydrological applications addressing natural hazard mitigation (floods, drought, landslides)
• Update and consolidate the GCOS requirements

POSITION OF THE ACTIVITIES IN THE INTERNATIONAL CONTEXT
State of the art:Classical products provide instantaneous estimates that cannot guarantee a right estimation of accumulated rainfall essential for hydrological studies.
Added value:• 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)
Main collaborations:TUWIEN (Austria)Deltares (The Netherlands)ETH (Switzerland)JPL, USDA, NASA (USA)NILU (Norway)
State of the art:River discharge and lake volume are usually obtained from in situ gauged station but recently the monitoring network is declining.
Added value: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.

BENEFITS FOR ITALY
1. Interest for the hydrological community to use satellite sensors for ungauged sites forestimating long time series and derive climatic trends, for Lakes (a CCI+ ECV), RiverDischarge (to be proposed by ASI to ESA CCI+ on behalf of IRPI). IRPI can be the primecontractor, leading an international team to tackle climatic trends in river dischargeworldwide.
2. Use of the developed products for natural disaster monitoring and management (theresponsible authorities, Civil protection and regional authorities have already manifestedtheir interest). The soil moisture based rainfall estimates have proved to be particularlyuseful for improving floods and landslides prediction.
3. Increased importance of the role of Italy in similar projects (H-SAF, SAF for hydrologyfrom 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 attractfunds from other related projects.
5. Italian labs’ increased skills to boost their international recognition in order to increasefund attractivity (e.g. H2020).
