OZONE AND METEOROLOGY MONITORING STARTED AUGUST 2001. - Air Monitoring Station in Castine, Maine

OZONE AND METEOROLOGY MONITORING STARTED AUGUST 2001. is an air monitoring station located at the Castine Municipal Garage in Hancock County, Maine, United States. The station is operated by the Maine Department of Environmental Protection's Bureau of Air Quality Control and contributes to the state's ambient air quality monitoring network. The station focuses on ozone and meteorological monitoring, which are critical for assessing air quality and understanding atmospheric conditions. Ozone is a criteria pollutant regulated under the US EPA's National Ambient Air Quality Standards (NAAQS). Meteorological parameters such as wind speed, wind direction, temperature, and humidity are measured to support ozone formation and transport analysis. This monitoring station supports the Maine DEP's efforts to protect public health and the environment by providing data for air quality index reporting, regulatory compliance, and research. Its location in a rural coastal area helps characterize background ozone levels and regional air quality patterns in the northeastern United States.

The station's location in coastal Maine provides representative data for regional air quality in the northeastern US. Ozone monitoring is essential due to the area's susceptibility to transported pollution from upwind sources. Meteorological measurements help understand local dispersion patterns and support air quality forecasting. The station contributes to the EPA's Air Quality System (AQS) network, ensuring data comparability and regulatory compliance.
