   Awesome PDF Editor

   PDF studio Pro is a fantastic product to create and edit your pdfs. It helped me transition from Windows to Linux as far as pdf editing is concerned. It has great features to enable the editing and annotating the pdfs. And unlike other paid and free software, it lets you import and export your settings to quickly restore your favorite layout of the product. To me this was one of the distinguishing features.

• AQHI – the superior AQI. Tracked only in Canada and Hong Kong. But you can calculate it yourself

  Iqair.com has this info. If you want to track IAQ (Indoor Air Quality) the same way – PM2.5 can be tracked cheaply and reliably, but I assume not the rest. Source: about 1 year ago

• Alternatives to Chiang Mai

  I would advise heading South anywhere around Phuket should be better. Consult iqair.com for live updates on burning season and air index. https://www.msn.com/en-xl/news/other/chiang-mai-air-still-the-worst/ar-AA19iwO4. Source: about 1 year ago

• Air Quality data over Joplin/Carthage

  On the other hand, if you use Weather.com's data they report it's only a perfectly fine "27" which is "good"-- and iqair.com says it's also fine. Ditto airnow.gov-- nothing unusual to report. Source: over 1 year ago

• What stinks downtown today?

  Iqair.com says the downtown air quality index is 112 which is on the high side. Source: over 2 years ago

• Not so purple anymore: Just a heads' up, Air is Hazardous (301 and up per purpleair chart), for everyone in the area right now.

  The best site for air quality I've found so far is iqair.com. They seem to update fast and are the most accurate I've seen, including the ugly numbers in the 300s, in line with it looking particularly bad outside, as of this writing. They also show wind currents, and you can click on the side options to show or remove particular map-markers. Source: over 2 years ago
