California Air Quality

In June of this year Google and the Environmental Defense Fund (EDF) released an interactive map of air quality in Oakland, California. The map was the result of a collaboration between EDF and Google.

For this collaboration Google's Street View cars were equipped with sensors to measure nitric oxide, nitrogen dioxide and black carbon as they drove the streets, while also capturing the panoramic Street View imagery used on Google Maps. Google has now completed air quality tests for the San Francisco Bay Area, Los Angeles, and California’s Central Valley.

So far no interactive maps have been released of this data. However the Google Blog has a few videos looking at the mapped results of these air quality measurements. The Aclima Blog has also published a number of data stories exploring the data. In addition Google says that air quality scientists can also request access to the data itself.
