In addition to bias-corrected climate scenarios, a number of climate indicators have been developed in the CLIMAPROOF project. They represent critical events for infrastructure and were designed together with experts from the relevant fields such as road infrastructure or hydrology. ## Freeze-thaw-days Monthly sum of days with tmin <= -2.2 °C and tmax > 0 °C ## Period 1981-2100 ## Scenario RCP8.5
