Getting hyper-local: Mapping street-level air quality across California
Most air pollution is measured at a city level, but air quality can change block by block, hour by hour and day to day. To better understand air quality on a more local level, we began working with our partner Aclima — to map air pollution across California using Google Street View cars—equipped with air quality sensors. Earlier this year, we shared the the first results of this effort with pollution levels throughout the city of Oakland.
We’re just beginning to understand what’s possible with this hyper-local information and today, we’re starting to share some of our findings for the three California regions we’ve mapped: the San Francisco Bay Area, Los Angeles, and California’s Central Valley (the Street View cars drove 100,000 miles, over the course of 4,000 hours to collect this data!) Scientists and air quality specialists can use this information to assist local organizations, governments, and regulators in identifying opportunities to achieve greater air quality improvements and solutions.
