Photographing Beijing's Air Pollution

Zou Yi, a resident of Beijing, has taken more than 1,000 images of the city's sky since 2013.

Yi takes two photos of the sky each day, posting them to Weibo (similar to Twitter) with information on air quality from China's Institute of Public and Environmental Affairs (IPE), an organization founded by Chinese environmental activist Ma Jun. IPE uses open data to engage public and private partners in the fighting against factory pollution.

Grantee Fred de Sam Lazaro speaks with Yi, whose work has inspired other residents of China to document the country's air quality.
