HOBERG-PINE SUMMIT Air Monitoring Station, Cobb, California | United States

HOBERG-PINE SUMMIT is an air monitoring station located at 9302 Fox Dr., Cobb, California, within Lake County. The station is part of the California Air Resources Board (CARB) network, which operates under the U.S. EPA's Air Quality System (AQS) framework. As an operational station, it contributes to the state's comprehensive air quality monitoring program. The station's last reported sample date is March 31, 2025, indicating ongoing data collection. While specific parameters measured are not detailed, CARB stations typically monitor criteria pollutants such as ozone, particulate matter (PM2.5 and PM10), nitrogen dioxide, and sometimes additional speciation or meteorological parameters. The station's siting in a rural area of Lake County provides representative data for regional air quality assessment. Environmental monitoring in this region is important due to California's strict air quality standards and the area's susceptibility to wildfire smoke and agricultural emissions. Data from HOBERG-PINE SUMMIT supports regulatory compliance, public health advisories, and research on air pollution trends. The station's long-term operation ensures continuity in tracking air quality changes over time.

Lake County, California, experiences a Mediterranean climate with hot, dry summers and mild, wet winters, which can influence air quality patterns. The region is prone to wildfires, which significantly impact particulate matter levels. The HOBERG-PINE SUMMIT station's rural location helps monitor background air quality and long-range transport of pollutants. Under the U.S. EPA's AQS network, such stations provide critical data for assessing compliance with National Ambient Air Quality Standards (NAAQS) and supporting public health protection.
