Block by Block Air Quality
• Your address can affect your health because air pollution can be 800% higher from one block to the next.
• We measure air pollution block by block repeatedly over months with sensor-equipped vehicles to map air quality, and combine dozens of measurements to calculate average pollution level at any address.
• For the Block by Block Air Quality section of this report, Aclima deployed a fleet of vehicles driven by local community members from August 1 to October 31, 2019, measuring fine particulate matter (PM2.5
), ozone (O3
), carbon monoxide (CO), carbon dioxide (CO2
), nitric oxide (NO), and nitrogen dioxide (NO2
), as part of an ongoing Bay Area-wide program

Current Air Quality
• Air quality changes throughout the day based on things like weather, traffic patterns, and emergency events like fires -- and your exposure to outdoor air pollution changes with it.
• In Richmond-San Pablo Physicians, Scientists, and Engineers for Healthy Energy
ran a network of 50 stationary devices across the community from January 2020 to March 2022. All the data went into the Aclima platform to be displayed in real-time during that period.
• Each device measured PM2.5
, and NO2
and is maintained so that it collects quality data. Stationary devices tell us the current air quality at the locations where they are installed.
