Beijing Air Quality: pm2.5

So how was 2016 for PM2.5 in Beijing?
Short answer: BIG improvement. The average has dropped from 158 in 2014 to 142
in 2015 to 133 in 2016! The best 2 months in the last 10 years were February
and August 2016, and February, with an average of 93.6, was the first month
to average under 100 since my records started in 2008. 4 of the top 10 months
in that time came in 2016, and 7 of the top 10 have been in 2015 and 2016.

Android App! My (un)employment situation has given me both time to program my own stuff and an impetus to work on new things to enhance my experience. To learn about Android programming I made an app for displaying the most recent readings on an Android phone. I am not going to release it officially, but will make the debug version available here if anyone cares to download it. You can also preview it online.
