Aclima, a San Francisco-based company that designs and deploys environmental sensor networks, is partnering with Google Earth Outreach to map and better understand urban air quality. The partnership will equip Google Street View cars with Aclima's mobile sensing platform. Aclima’s plug-and-play sensor modules are calibrated and adapted to provide detailed, environmental data. The networks measure a broad spectrum of variables, including noise, humidity, carbon monoxide, particulate matter, and methane. The technology was successfully tested in Denver, CO, where the Aclima team was able to instrument three Google Street View vehicles. The cars collected 150 million air quality data points over a month of driving around Denver.
