Overview
Hubbard Brook USFS-FES is an air monitoring station in Grafton County, New Hampshire, operated by the US EPA National Exposure Research Lab. It is part of a long-term ecological research site.
Hubbard Brook USFS-FES is an air monitoring station located in the Hubbard Brook Experimental Forest in Grafton County, New Hampshire, United States. The station is operated by the US EPA National Exposure Research Lab and is part of the broader Hubbard Brook Ecosystem Study, a long-term ecological research program established in 1955. This facility contributes to the US EPA Air Quality System (AQS) network, providing critical data on ambient air quality in a forested, rural setting. The station monitors criteria pollutants and other atmospheric parameters to assess air quality in a region influenced by both local sources and long-range transport. As part of the EPA's monitoring network, it follows rigorous siting and quality assurance protocols to ensure data representativeness and comparability. The Hubbard Brook site is known for its continuous, high-quality measurements that support research on atmospheric deposition, climate change, and ecosystem responses. Environmentally, the station plays a key role in understanding air quality in the northeastern United States, a region affected by industrial emissions, vehicle exhaust, and transboundary pollution. Its data help inform regulatory decisions under the Clean Air Act and contribute to the WMO Global Atmosphere Watch program. The station's long-term record is invaluable for detecting trends and assessing the effectiveness of air pollution control measures.
Environmental context
The Hubbard Brook Experimental Forest is a representative site for northern hardwood forests in the northeastern US. Air monitoring here captures regional background conditions influenced by urban and industrial sources from the Midwest and East Coast. The station's data on ozone, particulate matter, and nitrogen compounds are crucial for studying acid rain, eutrophication, and forest health. Its remote location provides a baseline for comparing urban and rural air quality.
