googlemobileWhile Google’s Street View cars have been busy snapping images of roads across the globe, including some of the most remote locations on Earth, a small handful of the smart vehicles have been quietly gathering data on something that’s much harder to see: air pollution.

Three of Google’s Street View cars were equipped with sensors from San Francisco startup Aclima and the roving sensor-laden vehicles spent a month driving around Denver last year, testing the air quality. The cars spent 750 hours on the city’s streets and collected 150 million data points about levels of various air pollutants, many of them caused directly and indirectly by gas-powered cars and fossil fuel-based power plants. The test was done in collaboration with NASA and the Environmental Protection Agency.

A key point of the test was to validate seven-year-old Aclima’s environmental sensor tech, which is a first step for the startup to offer the environmental sensors more widely. The company uses algorithms, big data analytics and machine learning to make its sensor data highly accurate. The company also makes it own hardware and has been developing what it says is the world’s smallest particulate matter sensor in collaboration with the EPA and Lawrence Berkeley National Lab.
