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.
