I don't know... I am only using it in the Bay Area. I noticed there are coordinates in the URL that one could try changing, but it is possible they are only running the model for the Bay Area right now?

I've also wondered if they have hand tuned the model to match local observations and geography in the Bay Area, and if it could generally apply elsewhere without a lot of manual work? In particular, it is mind blowingly accurate at getting the wind shadow around Angel Island, which is a complex thing to do, because it involves ocean wind that divides into at least 3 separate streams, and then recombines in complex ways. No other model I've seen can predict which of those 3 stream will dominate, but they usually can.

I've noticed the same with e.g. car navigation/map software- it generally works much better in the Bay Area where the developers and companies making them actually live, than elsewhere. I could imagine that in both cases the developers use it themselves in the place they live, and investigate/fix local errors themselves.




I did try altering the URL and didn't have much luck! It would make a lot of sense if Atmo was only running the model for a smaller area to keep costs from running up. My friend races in SoCal (the Channel Islands and Catalina are common destinations) and the wind shadows and streams are complicated there too.

Your observation about navigation software is accurate in my experience too :)
