the "local AQI" is usually from a single government sensor for 100 mile radius which is useless as pollution is highly localized (think neighbor idiots burning leaves all day) also doesn't tell you indoor air quality which where you sleep REALLY matters if the co2 is sky high best third party AQI network is PurpleAIR but even with them certain cities have few or none https://map.purpleair.com/air-quality-standards-us-epa-aqi https://map.purpleair.com/air-quality-standards-us-epa-aqi airgradient barely has any in some US states https://www.airgradient.com/map/ https://www.airgradient.com/map/ US doesn't even have mandatory air-quality sensors at airports, which it should because that's where most of the other weather measurements are coming from on most apps, even if you are 30-50 miles away

  > the “local AQI” is usually from a single government sensor for 100 mile radius What’s your source on this? IPhone’s AQI report says it’s from Breezometer, which links to Google’s Enterprise AQI offerings, which claim 500m resolution and multiple sources (“over 70 local indexes”). I don’t know but would speculate that Purple Air might be one of the licensed sources. https://mapsplatform.google.com/maps-products/air-quality/ https://mapsplatform.google.com/maps-products/air-quality/

  Even if measurement was perfect, people would have incentive to ignore it. Who wants to be told they can't do something, based on some claim that it might be bad for them in the very long term? People still smoke cigarettes and drink alcohol despite those being known to be bad for decades. Air pollution, like numerous other things like water quality and medical care, is too big to be made into a individual decision.
