Daily precipitation events
For historical data, the model performance of ERA5 and the meteoblue learning multi-model (MLM) is significantly better than the satellite observation CHIRPS2. Satellite observations typically have a larger model skill than numerical weather forecast models for heavy precipitation and close to the equator.

Annual precipitation sums
The meteoblue multi-model mix is significantly better than the historical reanalysis model ERA5 for annual precipitation sums. We recommend the use of the meteoblue learning multi-model (MLM) for the operational forecast, because daily precipitation events as well as annual precipitation sums are satisfactorily reproduced. Note that the measured precipitation sums in Romania are inaccurate, resulting in non-reliable values of the mean percentage error (MPE) in this region.
