Powered by its network of roving and stationary sensors, Aclima measures air pollution and greenhouse gases at unprecedented scales and block-by-block resolution. Its analytics software translates billions of scientific measurements into environmental intelligence for governments, companies, and communities. The company also features a free app, air.health, that maps address-level air and climate insights.

Founder + CEO Davida Herzl launched San Francisco-based Aclima in 2010. Herzl, who holds a JD from the University of San Diego, and her team of scientists work with government agencies like NASA and the EPA, and partner with Google to carry out comprehensive air-quality analyses and data maps used by communities to catalyze environmental policies and action.
