![]() This paper will cover some of the hydrological data sets available from HDISC, and the various tools and services developed for data searching, data subsetting, format conversion, online visualization and analysis, interoperable access, etc., to facilitate the integration of NASA hydrological data by end users. The Hydrology Data and Information Services Center (HDISC), part of the Goddard Earth Sciences DISC, has continually worked to better understand the hydrological data needs of the geospatial end users, to thus better able to bridge the gap between NASA data and the geospatial communities. There is a vast and ever increasing amount of data on the Earth's interconnected energy and hydrological systems, and yet one challenge persists: increasing the usefulness of these data for, and thus their use by, the geospatial communities. We will also discuss the activities that will be performed during CDOP in order to enhance and improve algorithms and processing schemes and extend them to satellites that will be operational in the 2010-2017 timeframe - with special emphasis on the GEO Meteosat Third Generation (MTG) satellite which is scheduled to be launched by EUMETSAT in 2017, and on the LEO Core Observatory of the Global Precipitation Measurement (GPM) mission which will launched by NASA and JAXA in 2013. We will present and discuss the basic algorithms for precipitation retrieval from satellite, that have been developed by CNR-ISAC. DPC is a major sponsor of the Italian participation to H-SAF, with increasing involvement in product validation and impact assessment activities. The emphasis of precipitation product generation in H-SAF is on near-real-time applications, as requested by the European hydrological community and, specifically in Italy, by the Civil Protection Department (DPC) - i.e., the Italian Agency which is responsible for disaster management. Access to products is currently limited to Institutions that participate in product development and/or validation activities. Products are generated in a pre-operational fashion, with a delay of few minutes to few hours from observation, depending on product and satellite data access. ![]() ![]() Whilst precipitation products continue to be developed and improved, major focus is now on product validation. These products are generated routinely at the Italian Centro Nazionale di Meteorologia e Climatologia Aeronautica (CNMCA), which is responsible of operational product generation and dissemination. VIS/IR imagers (SEVIRI) on GEO satellites (MSG).MW cross-track scanning radiometers (AMSU-A and AMSU-B / MHS) on LEO operational satellites (NOAA and MetOp).MW conically-scanning radiometers (SSM/I and SSMIS) on LEO satellites (DMSP).Precipitation products are being generated according to algorithms developed by CNR-ISAC in collaboration with the international community, by exploiting the following satellites and instruments: A follow-on Continuous Development and Operations Phase (CDOP) will start in September 2010 to provide long-term perspective (2010-2017) to the initiative. The development programme duration is 5 years, ending on August 31, 2010. In addition to products development and generation, the project includes a products validation programme and a hydrological validation programme. snow parameters such as effective cover, wet/dry discrimination and water equivalent.soil moisture in the surface layer and in the roots region.instantaneous and accumulated precipitation, including liquid/solid discrimination.The Project Plan focuses on the generation of the following products for the European and Mediterranean regions: The Italian Meteorological Service serves as "Host Institute" on behalf of 12 European countries. The EUMETSAT Satellite Application Facility on support to Operational Hydrology and Water Management (H-SAF) was established by the EUMETSAT Council on Jand started activity at the official date of September 1, 2005.
