According to Google, these vehicles are equipped with air sensors that measure nitric oxide, nitrogen dioxide, ultra-fine dust and soot (very small amounts of particles, almost never measured). Once the data in Amsterdam is analyzed, it will be shared with the public, scientists and other organizations. This research can raise awareness of air pollution and help people take action.
Google is conducting research in London, Copenhagen, Houston and Auckland. Using a Street View car developed by Aclima, Google released a map in 2017 showing block-by-block air quality information for Oakland, California. The map provides insights at the street level to understand where pollution originates. As of September 2018, Google has expanded its air quality mapping capabilities to more than 50 street-view cars around the world.
