PM2.5 way too low
-
Windy PM2.5 reports around 71 uG/cm3 for Quebec city YQB. Official government IQAir website report around 170 for same PM2.5 map. Why is it so different ?
-
@bernardmic I meant uG/m3 and not cm3
-
This PM2.5 layer in Windy is for the atmosphere but not at ground level.
Air quality stations are giving the content of PM 2.5 at ground level. So if you want to make a comparison you have to select Air quality stations in the POIs in Windy, displaying PM2.5 in μg/m3.
