Inspiration

Use something we learned from DEVFEST 16.

What it does

Analyze the historical data of PM2.5 and weather and tell something!

Important cities in China: Beijing, Shanghai, Shenyang, Guangzhou, Chengdu.

How I built it

Download the data from web (http://www.wunderground.com/, http://www.stateair.net/) by Python, analyze the data by R.

Challenges I ran into

First time to handle the data download from web.

Accomplishments that I'm proud of

We used what we learned from DEVFEST 16. We submitted something finally.

What I learned

Web scraping.

What's next for PM2.5 in China

Now we only analyzed Beijing. More cities, more parameters in the future.... More methods like time series...
