UC Davis Air Quality Research Center

What UC Davis Air Quality Research Center does

UC Davis Air Quality Research Center (AQRC) is a public research center within the University of California, Davis, established in 2005 and dedicated to atmospheric aerosol characterization, monitoring, and health-effects research. The center operates two flagship national air quality monitoring networks under contract to the US Environmental Protection Agency and the National Park Service: the Chemical Speciation Network (CSN), comprising more than 260 urban PM2.5 monitoring sites across the United States, and the Interagency Monitoring of Protected Visual Environments (IMPROVE), comprising approximately 160 monitoring sites across the United States, Canada, and South Korea. AQRC delivers nearly one million new measurement values annually for IMPROVE and supports PM2.5 NAAQS implementation, Regional Haze Rule tracking, and visibility trend analysis at Class 1 areas including national parks and wilderness areas. The center's analytical platform relies on Energy Dispersive X-ray Fluorescence (EDXRF), Hybrid Integrating Plate/Sphere (HIPS), Fourier Transform Infrared Spectroscopy (FT-IR), Thermal/Optical Analysis (TOA), and Gravimetric Mass Analysis, supported by custom-designed IMPROVE aerosol samplers and proprietary low-concentration XRF calibration standards.

The center is funded primarily through government research grants and contracts rather than commercial sales. Direct AQRC-hosted projects receive approximately $10M/yr in multi-collaborator funding, with UC Davis faculty collectively hosting approximately $50M/yr of air quality and climate research across campus. Approximately 31 staff operate the center, supported by 70+ affiliated UC Davis faculty forming one of the largest concentrations of air-pollution expertise at any US university. AQRC also participates in the EPA-funded San Joaquin Valley Aerosol Health Effects Research Center (SAHERC), administers the first UC-system PhD training grant in air quality, and hosts conferences including ASIC LATAM 2027 and the Wildfire Resilient Structures symposium. Analytical services—including XRF calibration standards, gravimetric mass, HIPS, TOA carbon, and FT-IR—are offered to network operators on an order basis, but the center does not market commercial products.

Distribution of AQRC's data and services occurs through public data portals (the EPA Air Quality System data mart and Colorado State University/CIRA's DataWizard platform) and direct federal contracting. The center's go-to-market is essentially a relationship-and-mandate-driven model: designation by EPA as CSN contractor and as principal IMPROVE operations manager provides a regulatory lock-in with the US federal government that defines both the customer base and the revenue stream.

Core offering

AQRC operates two of the largest national air quality monitoring networks in the U.S. — the Chemical Speciation Network (CSN, 260+ urban sites) and IMPROVE (~160 rural sites in the U.S., Canada, and South Korea) — on contract for the EPA and National Park Service. It also provides laboratory analytical services (EDXRF, HIPS, FT-IR, TOA, gravimetric mass) and XRF calibration standards, and conducts research on atmospheric pollutant characterization, health effects, and climate-relevant aerosol thermodynamics.

Product overview

UC Davis Air Quality Research Center operates two primary national monitoring networks—Chemical Speciation Network (CSN) for urban PM2.5 and IMPROVE for rural visibility—as core products. The center provides comprehensive laboratory analysis services including Energy Dispersive X-ray Fluorescence (EDXRF), Hybrid Integrating Plate/Sphere (HIPS) for light absorption, Fourier Transform Infrared Spectroscopy (FT-IR), Thermal/Optical Analysis (TOA) for carbon, and gravimetric mass measurements. These interconnected monitoring and analytical services support regulatory compliance assessment, visibility tracking, and air quality research across approximately 160 IMPROVE sites and over 260 CSN sites throughout the United States, Canada, and South Korea.
