Mountain View 23 Air Monitoring Station, Mountain View, Hawaii | USA Environmental Monitoring

Mountain View 23 is an air monitoring station located at 18-1235 Volcano Road in Mountain View, Hawaii, United States. Operated by the Hawaii State Department of Health, the station is part of the national ambient air quality monitoring network and contributes to the US EPA Air Quality System (AQS). The station is situated in a rural area near Hawaii Volcanoes National Park, providing representative data for the region's air quality. The station operates under the regulatory framework of the US Clean Air Act and EPA monitoring requirements. It likely measures criteria pollutants such as ozone, particulate matter, and sulfur dioxide, though specific parameters are not detailed. The station's last reported sample date is June 30, 2025, indicating ongoing data collection. As part of the Hawaii network, it supports compliance with National Ambient Air Quality Standards (NAAQS). Environmental monitoring in Hawaii is critical due to volcanic emissions (vog) and unique island meteorology. Mountain View 23 helps track air quality impacts from volcanic activity and local sources, providing data for public health advisories and regulatory decisions. The station's long-term operation supports trend analysis and community awareness.

Hawaii's air quality is influenced by volcanic emissions from Kilauea, which release sulfur dioxide and particulate matter, creating vog that affects downwind areas. Mountain View 23 is positioned to monitor these impacts, as well as background conditions. The station's siting is representative of rural island environments, and its data contributes to understanding long-range transport and local pollution patterns. Reporting continuity is maintained through the Hawaii State Department of Health, ensuring reliable records for regulatory compliance and public information.
