Weather Data

Real Weather Data

Weather data is valuable to any sim as it can allow developers or modders to implement or enhance weather features such as accurate historical weather, quasi-realistic weather scenarios, weather progression algorithms, calculating weather metrics (such as averages, medians, standard deviations, etc.), and more.

Racing Circuits Real Weather Data

This dataset helped support the Crew Chief GTR2 Enhancements Plugin Real Weather feature which provides realtime and slot-based, algorithm-generated quasi-realistic weather scenarios for GTR2.
