Precipitation products comparison over European and African areas: methodology and data used


Marco Petracca talks about the validation of H-SAF precipitation products.

Length: 31 minutes


The H SAF Precipitation Product Validation Group (PPVG) annually analyses all the operational precipitation products released by the consortium in order to check the quality and evaluate their performance over time. The Quality Assessment (Q.A.) service is carried out by comparison with precipitation data used as reference. The comparison over the Europe is performed with radar and rain gauge data belonging to eight European countries: Belgium, Bulgaria, Germany, Italy, Hungary, Poland, Slovakia and Turkey. The methodology used to evaluate the quality of precipitation products is common to all member states through the use of a same algorithm (named Unique Common Code). Over African areas the comparison is performed with respect to the Dual-frequency Precipitation Radar (DPR) products of the Global Precipitation Measurement (GPM). Data used, methodology applied, and results obtained will be presented.
