More accurate estimates of the impact of climate change on road weather in Finland

More accurate estimates of the impact of climate change on road weather in Finland

For the first time, the FMI's road weather model was successfully combined with the regional climate model.

With the help of this method, more accurate estimates can be made of the impact climate change has on road weather in Finland. The road transport sector benefits from the improved accuracy of the data, especially in northern latitudes.

Previous studies have made indirect estimates regarding future road weather based primarily on the changes in temperatures and precipitation. The regional climate model can be used to generate data on the current and future climate, which can then be used in the road weather model.
