IVAN Air Monitoring

Poor air quality can harm your health. Take action to reduce your exposure to air pollutants. Use the list or map to view current air quality levels at your nearest air monitor. Sign up to receive alerts when the air quality near you is unhealthy. Scroll down to learn more.

About the network

Poor air quality is linked to many health problems, including asthma, cancer, heart disease, premature birth, and premature death. Central California Environmental Justice Network is working to expand their network of existing monitors and measure methane. The network will provide local, real-time air quality information for residents to take action and protect their health from poor air quality.

CCEJN plans to:

  • Install additional methane monitors throughout the San Joaquin Valley
  • Provide air monitoring data to the community via the website ivan-fresno.org/air and an alert system
  • Engage regional and state air quality agencies in the process of monitoring

What is being monitored and why?

  • Particulate Matter - Particulate matter (PM) pollution can harm health, such as causing breathing and heart problems. Having current air quality information helps us to know when to take actions (such as staying indoors) to reduce exposure when pollution levels are high. The monitoring data can also help us to understand air pollution trends in Kings County and Fresno County. The goal is for residents to have a better understanding of what air quality is like in their community.
  • Methane – Methane is a colorless and odorless gas that is emitted naturally and by human activity. Methane is a greenhouse gas that strongly contributes to climate change. Methane is non-toxic and is not directly harmful to human health. However, methane may be emitted at the same time as harmful pollutants, particularly during oil and gas extraction. We plan to monitor methane where community members have raised concerns near dairy and feedlots, solid waste landfills, and oil and gas extraction.


When using this information, please note the following:

  • In order to provide air quality information in real time, the data presented on this website are not validated or verified
  • The air quality levels are for particulate matter (PM) only. Other air pollutants, such as ozone, may be present, even when PM levels are low.
  • These data do not come from regulatory monitors and cannot be used to infer violations of the law
  • Data on this website should be considered preliminary and used with discretion
