So, Purple Air and IQAir are both giving US PM 2.5 numbers in the fifties, which is yellow/moderate. Normally this would mean Environment Canada would show a ~2 on the AQHI because the index thinks ozone is more dangerous than small particulates, which is just wrong when it comes to forest fire smoke. But it's currently showing 4 (yellow/moderate) which is similar to the PM 2.5 and probably fairly correct. I wonder why and if something changed (did they finally update the index)? Or is there something else terrible going on?
