Overview
Glendora is an operational air monitoring station in California, part of the South Coast Air Quality Management District network. It provides ambient air quality data for the Los Angeles region.
Glendora is an air monitoring station located at 840 Laurel in Glendora, California, within Los Angeles County. Operated by the South Coast Air Quality Management District (SCAQMD), this station is part of a comprehensive network that monitors ambient air quality in the South Coast Air Basin. The station is operational and contributes to regional air quality assessments. The station operates under the regulatory framework of the U.S. Environmental Protection Agency's Air Quality System (AQS), which sets standards for criteria pollutants such as ozone, particulate matter, carbon monoxide, nitrogen dioxide, sulfur dioxide, and lead. SCAQMD manages a dense monitoring network across Southern California, with stations typically equipped with federal reference or equivalent methods for continuous or periodic sampling. The Glendora station's last reported sample date is September 30, 2025, indicating ongoing data collection. Environmental monitoring in the Glendora area is significant due to its location in the Los Angeles Basin, which faces challenges from ozone and particulate matter pollution driven by vehicle emissions, industrial activities, and geography. Data from this station supports public health advisories, regulatory compliance, and air quality management strategies. The station's siting is representative of suburban exposure, providing valuable information for community-level air quality assessments.
Environmental context
The Glendora station monitors air quality in the San Gabriel Valley, an area influenced by urban and suburban emissions, including traffic and industrial sources. The region experiences high ozone levels during summer due to photochemical reactions, and particulate matter from wildfires and local sources. The station's data helps track compliance with National Ambient Air Quality Standards (NAAQS) and supports SCAQMD's air quality management plans. Parameter coverage typically includes criteria pollutants and meteorological variables, though specific measurements are determined by the agency's network design.
