John Francishuh, firesmoke.ca seems to be down today. There's definitely something in the air, although the air quality index is only a 3...the airport is calling it "mist" and "haze", but weathercan is calling for "local smoke" this afternoon, and a worsening air quality forecast into Tuesday night
mrchan@johnefrancis US AQIs across Ottawa in the triple digits on Purple Air and IQ Air
@mrchan is it forest fire smoke, or some other air pollution?
I did see a model image with a big swath blowing from BC/AB all the way to the east, but it wasn't supposed to be near ground level.
Gross!
@johnefrancis No idea. IQ Air showing prevailing winds from S and SE, not really any fires of note in those directions. Maybe just general pollution?
