The China Air Quality widget shows the real-Time Air Quality Index (AQI) for more than 300 cities in Mainland China, Hong Kong and Taiwan.

The Air Quality data sources varies depending on the cities:

- The US Embassy PM2.5 data is used for Shanghai, Beijing, Chengdu, Shenyang and Guangzhou.
- The China Ministry Environment Pollution Departement PM10 data is used for all other cities in China.
- For Hong Kong and Taiwan, the respective Environment agencies PM2.5 data is used.

The overall AQI, PM2.5 and PM10 measurements are updated every hour.


In order to install the widget, you need to insert it on the homescreen:

- If you are using Android 4.0 (Ice Cream sandwich), select the "All Apps" icon (usually on the top-right corner), then the widget tab, and click on the "Beijing Air" widget.
- If you are using any other version below 4.0, you need to long-press in an empty area on the default home screen and select "Widgets", and then "Beijing Air".
