It's true that local air quality can vary a lot, but there aren't enough sensors in the world to give everyone street-by-street data. I think it's still useful to have a fast source for real time "best available" data. I am thinking about ways to add context and allow people to judge the data quality without adding features like maps that would make the site much slower.
- lucideer 7y agoI agree, but I was just pointing out that I think PurpleAir is a better source for this because aqi.today is (unintentionally) misleading without the context offered by PurpleAir. I know that the air pollution is very bad around my area as there was a comprehensive one-off detailed study done of every area of the city in 2017 which showed it to be, and the causes of it have not since changed. The lack of realtime sensors in my area though would mislead aqi.today users to think that everything's rosy here. At least with PurpleAir one get an immediate idea of a lack of data in one's area. This isn't intended as an outright criticism: I guess aqi.today could be made more informative by adding either some quick context, or a disclaimer, into the UI.
