Icon weather model or ECMWF is more accurate?

The weather forecast is based on the meteorological model. Various weather forecasts have different emphases, such as general weather forecast, abnormal weather forecast, skiing weather forecast and agricultural weather forecast. ECMWF (european centre for medium-range weather forecasts) is a European model with a forecast interval of 3 hours and an accuracy of 9 kilometers. It is the most accurate model that people can use at present, and it is also recognized as the first in the world at present. The disadvantage is that the data of China is only updated twice a day.

ICON can detect changes in the ionosphere, such as aurora. ICON can directly measure particles and their motion in the ionosphere, which helps us to better understand the physical characteristics of the upper atmosphere.
