This is the first time I've heard of this weather API. I'll check it out.
Okay cool, I'm diving in and doing the same. I feel like I trust NOAA/NWS data more than other sites, since I haven't quite figured out where OpenWeatherMap / Open-Matteo are getting their data.
Well this is what ChatGPT says:
ChatGPT - Weather Data Sources
*
OpenWeather * ingests
real‑time observations from thousands of official and volunteer
surface/upper‑air stations (METAR, CWOP, ASOS/AWOS, etc.), weather‑radars and satellites, then blends them with major global NWP models (GFS, ECMWF, UK Met Office, its own OWHL model) before it re‑distributes the data through its APIs.
*
Open‑Meteo * does
not pull live station readings itself. Instead it serves output from open, high‑resolution
numerical weather‑prediction models that national meteorological services publish as open data (ICON‑D2, HRRR, GFS, IFS, UKMO, ARPEGE/AROME … ≈ 15 models today). For past weather it offers re‑analysis grids (ERA5, ECMWF‑IFS archive, etc.) that already contain the assimilated observations from stations, buoys, aircraft and satellites.
Also seems that those providers are limited to data refreshes of 10 minutes.
I would like to get weather alerts working as a ticker in OBS too, and I should be to do that through that API too. This would be an example of where I could pull the data from for weather alerts at a location near me.
