A forecast that knows when it is unsure

Physon runs on STA, our own forecasting architecture. It is not a chatbot. It forecasts in two parts. Its inputs are open data: ECMWF and Copernicus ERA5 (CC BY 4.0). A place shows forecasts only after Physon passes its exam there.

LawsWhere the sun is and how much light a clear sky gives (physics), and the usual daily rhythm of heat, wind and pressure here (from past years).
LearningHow today departs from the usual, learned from this place's own history, hour by hour, with a memory of what came before.
Confidence, alwaysEvery value carries a confidence level: High, Medium or Low. When Physon is less sure than usual, it says so.
