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 much more, making for more immersive, varied, and interesting weather experiences.

Racing Circuits Real Weather Data

Latest Release: 2024-09-19
- New locations added: Adria International Raceway, Castle Combe Circuit (Wiltshire, England), Grand Prix of Cleveland (Burke Lakefront Airport), Falkenbergs Motorbana, Gateway Motorsports Park (World Wide Technology Raceway), Circuito de Jerez, Ring Knutstorp, Mondello Park, MotorLand Aragón (Circuito de Alcañiz), Nelson Ledges Road Course, Salzburgring
- Improved real weather data weather states to improve preciseness of stats. For example, in meteorology, a Thunderstorm may or may not have Rain. So, stats were improved to be more precise in cases like this.

Description

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