@idefix37 I'm not familiar enough with all of the various weather models and their different layers and predictions. I know that Windy has a worldwide PM2.5 layer from ECMWF that doesn't allow any forecast selection (but presumably could, to specify smoke plumes?). There are a variety of English language regional and national smoke forecast models I do know about: the two in the title from NOAA, Canada has one called Blue Sky [that also covers the US], Australia has a smoke module in its AQFx model. Given the current layout of Windy and the presence / availability of models that cover limited time and geographic areas I'm confused by your implication that something has to cover everywhere for consideration for inclusion.

@idefix37 Oh I see. Yes that works well. I was using C0 before but this works much better.
