This May, Aclima and San Diego County announced a partnership to bring hyper-local air quality data and insights to San Diego communities, regulators, and policymakers. Aclima’s air quality mapping and analysis platform provides next-generation diagnostics of critical air pollutants and greenhouse gases at block-by-block resolution. Today, we are giving the public visibility into air quality in their neighborhoods on our website. This is a first step towards making air pollution visible to San Diegans where they live, work, play and learn, so they can take action to improve air quality and protect their health.
