Drivers who helped collect data for West Oakland

What We Did

• We measured important air pollutants across West Oakland: PM2.5, ozone, carbon monoxide, and carbon dioxide

• We generated 5.2 Million Data Points, collected over 3,000 miles July 1st through September 30th

• Working closely with our project partners, West Oakland Environmental Indicators Project (WOEIP) and Rising Sun Center for Opportunity, we conducted dozens of user interviews and surveys with community members to inspire this tool

• We mapped throughout the whole quarter with greater frequency in July

• We will release another quarterly air quality map in early 2020

In Detail - Location by Pollutant

Hyperlocal air quality mapping is a new capability. California and National air quality standards are calculated using a small number of stationary monitors and averaged over specific time periods, typically every 24 hours and yearly. Aclima’s method is different — we cover every street with multiple passes for quarterly averages at very precise locations. However, government standards help provide context about what pollution levels are of concern.

PM 2.5
PM 2.5 Average: 11.2 µg/m³

Emitted directly from a combustion source or formed in the atmosphere from complex chemical reactions, particulate matter (PM2.5) is one of the primary pollutants public health officials care about because it is linked to asthma, lung cancer, and deaths from cardiopulmonary diseases. You can reduce your exposure to PM2.5 by staying indoors, particularly in buildings with good ventilation and filtration systems. If outside, reduce overall activity levels.

Next steps - What you can do

Whether you only have a few seconds or you want to devote more time to reducing air pollution, we’re building a library of actions you can take. Got a great idea you want to share? Let us know!

Three things you can do right now:
  1. Protect your health and do your best to limit your time in higher-polluted areas identified on the Aclima hyper-local air quality map.
  2. Make plans to join the next Community Air Protection Program monthly Steering Committee meeting or email to get involved.
  3. Share this site with your neighbors, family, and friends in the community.
Three things you can do this week:
  1. If you see something that you think is causing more pollution than it should, submit a complaint to your Bay Area Air Quality Management District.
  2. Sign up and get more involved in local issues through groups like the West Oakland Environmental Indicators Project and Rising Sun Center for Opportunity.
  3. Follow and share your ideas on the Air District’s Open Air Forum.
Three things you can do long-term:
  1. Let your local government know that clean air matters to you. Any member of the public can participate during the regularly scheduled public board of supervisors meetings.
  2. Learn more about air pollution with this free air quality course.
  3. Tell us how we can make this app better and easier to use!
