In 2008, everyone knew Beijing was polluted, but we didn't know how much. That year, the US Embassy in Beijing installed a rooftop air-quality monitor that cost the team about as much as a nice car. The device began automatically tweeting out data every hour to inform US citizens of the pollution’s severity (@beijingair).

For the first time in China, publicly available data [...] often painted a bleaker picture than did the Chinese official pronouncements. [...] At first, the Chinese government pushed back and pressured the Embassy to stop releasing the data, saying that “such readings were illegal”. Fortunately, the Embassy stood its ground.

In 2010, it became official: Beijing’s air quality was deemed "crazy bad" by the Embassy when the pollution exceeded the bounds of the EPA's air quality index.
