This year saw a big jump in public interest in not only air pollution awareness, but also interest in finding out the air quality reading in their area. There are a number of websites out there that help you with this. The main international sites are aqicn.org and airvisual.com. I have used them both, but I find AirVisual more useful. Mainly because AQICN seems to rely a lot on government monitoring stations that are not always reliably updated. Yes, AirVisual sometimes has these problems, but most of their stations are run by ordinary people and schools and these are updated hourly. AirVisual also has the advantage that they have a good app for smartphones and widgets that webmasters can put on their blogs like at the bottom of this post.
