I am involved on a project that aims to analyze data from road weather stations, like the ones you can see from a German site here:
https://www.dwd.de/EN/ourservices/bufr_extensions_national/bufr_extensions_national.html https://opendata.dwd.de/weather/weather_reports/road_weather_stations/
Does anyone know where I can find this kind of information from other countries? I am specially interested in analyzing Water Film Thickness.
