Large-scale study for Europe (2012)
- Percent correct hourly = 85%
- Amounts: 90% within +- 30%
- HSS* 0.3 - 0.6 (>1mm/day)
- Consistent over continents
Used on all meteoblue simulations.
meteoblue can forecast more than 75% or 85% of all precipitation events with more than 2 or 5 millimetres (mm) correctly 3 days in advance. This includes forecasting the days on which such events will not occur. Looking at precipitation events of 2 mm, meteoblue can forecast 50% of those 6 days in advance, and more than 60% one day in advance.
What does that mean?
Personally: If meteoblue forecasts rain 1 day ahead, it will arrive in at least 2 of 3 cases; and a meteoblue rain forecast of 6 days ahead has more than 50% chance to occur.
Technically: with meteoblue precipitation forecast models, you have statistics that are so solid that you can calculate economics of intervention for precipitation events based on the meteoblue forecast.

Large-scale study for World (2016)
In this study on almost 9000 weather station, the new meteoblue multi-model precipitation forecast showed accuracy superior to ECMWF.
