7 The SAF Concept In 1992 EUMETSAT adopted the concept of a Distributed Application Ground Segment including: the EUMETSAT Central Facilities in Darmstadt and a network of elements known as Satellite Application Facilities (SAF), as specialised development and processing centres. SAFs utilise the specific expertise available in EUMETSAT's Member and Cooperating States. The SAF network complements the production of standard meteorological products derived from satellite data at the central facilities in Darmstadt and also distributes user software packages. SAFs are developed by consortia of organisations from the EUMETSAT Member States and Cooperating States, and are located at the National Meteorological Services in Member States.

8 Satellite Application Facilities (SAFs) in Europe Member State Cooperating State Support to Nowcasting and Very Short Range Forecasting Ocean and Sea Ice Climate Monitoring i Numerical Weather Prediction Land Surface Analysis Ozone and Atmospheric Chemistry Monitoring GRAS Meteorology Support to Operational Hydrology and Water Management SAF Consortium Member Additional Met Service Users

9 Hydrology SAF SAF on Support to Operational Hydrology and Water Management Host institute: Italian Meteorological Service (USAM) SAF products focuses on precipitation soil moisture snow parameters utilisation of these parameters in hydrological models and NWP (validation programme) The H-SAF started Development Phase in September 2005 and will enter its Continuous Development and Operations Phase (CDOP) in September 2010

10 H SAF : precipitation p products Instantaneous Rain Rate from cross-track and conical scanning microwave sensors (AMSU/MHS, SSM/I SSMIS)

11 H SAF : precipitation p products Instantaneous Rain Rate From blending microwave sensors with Geostationary Meteosat IR image (pre- operational) From morphing microwave rain-rates with advection derived d from Meteosat t IR images (in development)

12 H SAF : precipitation p products Accumulated precipitation 3-24 hours, from IR + MW information Assimilated product (NWP model) as backup information

14 H SAF Validation Programme Objective: to perform independent validation of the usefulness of new satellite products for e.g.: Fighting against floods, landslides, avalanches Evaluating water resources Activities: downscaling, upscaling modelling from observed fields to basin level Fusion of satellite-derived measurements with data from radar and rain gauges networks Assessment of the impact of satellite- derived data in hydrological applications

15 Transferring validation tools to routine quality monitoring Operational products require: Scientific validation (during development) Product validation (after implementation and regularly during operations) Routine quality monitoring (real-time) to detect sudden changes as well as long-term trends in the product quality Quality indicators (with all products) to pass the information from routine monitoring to users

16 Routine quality monitoring Based on the product statistics (max, min, reg. averages,...) Based on algorithm-internalinternal information (internal consistency, goodness of fit,...) Based on comparison with other products from the same data source (other rain-rate algorithm for the same satellite,...) Based on comparison with completely independent data (ground-based rem. sensing data, in-situ data, models,...)
