More and higher accuracy

New studies show the accuracy of meteoblue models for both forecasting and historical weather data

meteoblue has conducted extensive comparisons of model simulations with measurements of temperature, precipitation, wind and radiation.

The accuracy obtained for temperature forecasting (calculated as MAE = mean absolute error) are the highest ever published - in a study with global extension - for the forecast 1 to 180 hours ahead. Precipitation accuracy of current meteoblue forecast is even higher than historic reanalysis weather data sets (ERA5). Only local measurements achieve higher accuracy.
With these new studies, users can get precise information about how accurate weather information is for any place on the planet. Thereby, they can now make uniquely science-based decisions on which weather data to use for their purposes.

Dear User, thanks for your comments. We have updated the text to include the explanations. All explanations and more can be found on the verification pages accessible via the links in the text.

It is great that you are monitoring the accuracy. I find it disappointing that the graph you present is so poorly annotated. What is MAE. What does it mean "forecast hours"?
