The University of California Riverside's (UCR) Center for Environmental Research and Technology (CE-CERT) in collaboration with the UCR School of Medicine's Center for Healthy Community's (CHC) Community Air Board (CAB) deployed 4 air quality sensor systems to date in the Riverside community starting in 2025 as part of the Sensor Library Program. All sensors deployed in the community are Kunak Air Lite units that measure PM_2.5, PM₁₀, Ozone (O₃) and Nitrogen Dioxide (NO₂). Data from sensors can be graphed, compared, and downloaded using the JustAir dashboard.
