MOTIVATION:
• Croatian Adriatic coast is one of the rainiest areas in Europe
• Lack of radar coverage along the coast
• No precipitation data over the sea

Validation efforts• Verification still being performed– currently on case-to-case basis
• Comparison with:– radar data where available– Raingauges data – Aladin and ECMWF model forecasts

Summary• From case to case observations it seems that precipitation
products from SAFNWC tend to underestimate low precipitation rates
• For intensive precipitation cases there is a signifficant difference between PGE14 (physical retrieval) and PGE05 products
• PGE05 seems to underestimate hourly accumulation rates • PGE14 seem to have more structures (features) in
precipitation field
