Interactive: Beijing Slider
In the window below, a slider can be dragged across the picture to compare between a blue-sky day and a really smoggy day in Beijing, pixel by pixel. These two days, June 19 and 22, 2009, were selected from our Beijing Air archive, photographs by Lin Yang and/or John Billingsley.
Two Perspectives: Beijing Dust Storm
The dust storm has become a seasonal eye sore and throat sore for Beijing residents and those who pass by during gritty spring days. Here below is a late March day when sand, blown from the Gobi out in the west engulfed the region and reduced visibility. Also presented is the same day's satellite image via NASA, showing the widespread effects of the dust storm. Photographs by Lin Yang and/or John Billingsley.

Two Perspectives: One-Day Apart in Beijing
Presented below are four images of Beijing on two consecutive days: December 21 and 22, 2010. The two large images were taken by satellites via NASA, the other two from the ground. One can see that the layer of thick smog can sometimes blanket the North China Plain and even the adjacent seas. Photographs by Lin Yang and/or John Billingsley.

Archived Worst Week in Beijing (Plus Satellite Views)
During the four years (2007-2011) of Beijing Air, we've seen a rollercoasterof ups and downs in the city's air quality. Being able to see a few straight days of blue-sky is a luxury. During the Christmas week of 2007, smog covered the skies and API, China's government gauge of pollution levels, registered a maximum of 500 and a 420. Photographs by Lin Yang and/or John Billingsley, satellite images via NASA.
Watch: Longing for Blue Skies (with MediaStorm)
We produced this video we for Beijing Air, launched in July 2008. Although the Chinese government had invested 120 billion yuan to clean up its air before the Olympic Games, air quality has remained a major concern.
