Hailing from a place which experiences 200+ ug/m3 of PM 2.5 each season it's hard for me to tell what sort of mixture of fog and smog we are having on a given day - they vary only slightly in colour.
But smog definitely significantly reduces the amount of sunlight reaching the ground and that can be felt.
EDIT: the unit should have been ug/m3, not ppm.
- cyberdrunk 6y agoIn my area, it's easy to tell - the winter smog (from burning coal and god knows what else) stinks.
- hexbinencoded 6y agoWhat is that in the standard raw metric of air quality in micrograms / cubic meter?
- Tade0 6y agoAssuming soot, 200ppm = 100μg/m3, but I double checked my source and turns out it indicates in μg.
