Overview
Coso Gate is an air monitoring station in Inyo County, California, operated by the Great Basin Unified APCD. It provides ambient air quality data for the remote Coso region.
Coso Gate is an air monitoring station located in Inyo County, California, United States. The station is operated by the Great Basin Unified Air Pollution Control District (APCD) and serves the remote Coso area, contributing to regional air quality surveillance. The station operates under the U.S. EPA's Air Quality System (AQS) framework, which sets standards for criteria pollutants such as ozone, particulate matter, and nitrogen dioxide. As part of the Great Basin Unified APCD network, Coso Gate likely monitors pollutants relevant to the arid, high-desert environment, including dust and ozone precursors. The station's last reported sample date is June 30, 2025, indicating ongoing operation. Environmental monitoring in the Coso region is important due to its proximity to geothermal energy facilities and military training areas. The station helps assess air quality impacts from these activities and provides baseline data for the surrounding Mojave Desert ecosystem. Its data supports regulatory compliance and public health protection in a sparsely populated but industrially active area.
Environmental context
The Coso Gate station monitors air quality in a high-desert environment influenced by geothermal energy production and military operations. Parameter coverage likely includes criteria pollutants such as ozone and particulate matter, which are relevant for assessing impacts on visibility and human health in the Mojave Desert. Siting representativeness is typical for remote background stations, providing baseline data away from urban sources. Reporting continuity through the Great Basin Unified APCD ensures adherence to EPA AQS standards.
