VATSIM weather source?

Somehow I think VATSIM weather is really accurate even for the airports that don’t have NOAA METAR station. Makes me wonder what source are they actually using. Any ideas?

I believe they are using NOAA ( METAR API.


Surprised to see just one response. Is it a mystery?

No, it’s the answer, from VATSIM Discord :slight_smile:

I think there’s something more than just METAR as I said in my initial post. They have very accurate conditions for non-METAR airports as well.

I posed the question on their Discord and that was the same response from several controllers. But you may be write, just passing along what I saw.

here is how to get the public NOAA weather with a browser request

use decimal degrees for LAT LON
example request,-77.0352
