Community Air Monitoring Project

We’re monitoring air quality in the Carquinez Strait communities (Rodeo, Crockett, & Vallejo)!

Would you be interested in having an air monitor installed on your property? Email us at rodeocitizens@gmail.com.

FAQ

Question 1: What is this project?

This is our community’s project to understand the air we breathe in Rodeo, Crockett, Vallejo, and surrounding areas. Funded by a state grant (California Air Resources Board, or CARB), this is a partnership between the Rodeo Citizens Association (RCA), Citizens Air Monitoring Network (CAMN), Contra Costa Resource Conservation District (CCRCD), and Hyphae Labs. The goal is to understand and document local air pollution—specifically fine particulate matter (PM2.5)—by combining advanced wind and terrain modeling with a network of air sensors and air monitors. The goal is simple: to know exactly what’s in our air so we can protect our health, our families, and advocate for cleaner air together.

Question 2: Where will the sensors go?

We need to place sensors in specific spots to get the full picture. We’re looking at three main types of locations across Rodeo, Crockett, Vallejo, and Hercules:

  • High Points for “Hubs”: We need 1-2 high locations (like hilltops or tall buildings) to act as central receivers for data. Examples: Crockett Hills Regional Park, Suribachi Hill
  • Wind Sensor Lines: We’ll create two main “listening lines” of wind and pollution sensors. One line will follow the common wind path from the refinery toward Crockett and Vallejo. Another will cut across neighborhoods. These need clear, unobstructed spots in Rodeo, Crockett, & Vallejo.
  • PurpleAir Sensors: We’ll place smaller air quality monitors at key community spots across Rodeo, Crockett & Vallejo—especially places you’ve told us have concerns.

Question 3a: I own a home, business, or property. Can I host a sensor?

Yes! We need your help. Hosting a sensor is a direct way to contribute to community science.

  • What we’re looking for:
    • For Wind Sensors & Hubs: Rooftops, poles, or open areas on higher ground with a clear view of the sky (no tall obstructions like dense trees).
    • For PurpleAir Sensors: Secure spots on homes, businesses, or community buildings in neighborhoods of concern.
  • What’s in it for you? You’ll get direct access to hyper-local air quality data for your property and the satisfaction of supporting a vital community health project.
  • What’s required? We need your permission to install a small, discreet device. For most sensors, we’ll use solar panels—they won’t use your home’s electricity or WiFi. For some neighborhood PurpleAir sensors, we may ask to use an outdoor outlet or WiFi connection, which we’d discuss in detail first.
  • How to get started? Please contact us! We’ll answer all your questions, check if your location is a good fit, and handle all installation with a simple permission agreement.

Question 3b: How long would the sensor be on my property?

About 1.5-2 years.

Question 4: How else can I get involved?

  • Attend our Community Forums: Gain knowledge on local air quality and stay informed on the health of your community. Community Forums will begin in early 2026, please fill out this form to sign up for reminders: https://forms.gle/mnuZZFRLmyVw6XREA
  • Be a Community Scientist: Help choose where to put sensors, join installation workdays, or learn to check the data dashboard. We’ll have fun field trips and workdays!
  • Spread the Word: Talk to your neighbors, landlords, or local business owners. Do you know someone with a great rooftop in Rodeo & Crockett or a good pole in Vallejo? Connect us! Email us at rodeocitizens@gmail.com.
