What is OWWL?
Ozone Where We Live (OWWL) is a NASA project that studies air quality in California’s San Joaquin Valley. Kids and families can help by placing simple sensors at homes, schools, or other locations—or even by flying sensors on planes—to collect data that helps scientists track and predict pollution.
How does it work?
NASA scientists team up with community volunteers to explore and measure air quality in the San Joaquin Valley, giving you a chance to be a real-life Earth scientist!
Airborne component: Volunteer pilots carry small ozone sensors on their regular flights to collect important data near the ground, helping NASA check and improve satellite measurements.
Ground-based component: You, your family, or your school can host sensors to track ozone and other gases in your neighborhood. The data you collect helps scientists understand pollution, make better predictions, and share real-time air quality information to keep your community safe and informed.
