Overview
Claryville is an operational air monitoring station in Ulster County, New York, part of the CASTNET network. It provides long-term data on atmospheric deposition and ambient air quality, supporting EPA regulatory programs.
Claryville is an air monitoring station located at 47 Southern Way in Ulster County, New York, United States. It is part of the Clean Air Status and Trends Network (CASTNET), which monitors the effects of air pollution on ecosystems. The station is operated by Mactec, Inc. and has been providing continuous data, with its most recent sample collected on December 10, 2024. As a CASTNET site, Claryville measures key atmospheric parameters including ozone, sulfur dioxide, nitrogen compounds, and particulate matter. These measurements contribute to understanding regional air quality trends and the effectiveness of emission reduction policies under the Clean Air Act. The station's rural location in the Catskill region provides representative background conditions for assessing long-range transport of pollutants. The data from Claryville supports research on acid deposition, eutrophication, and visibility impairment. It also aids in validating satellite observations and informing ecosystem management. The station's consistent operation over many years makes it a valuable resource for tracking changes in air quality and climate interactions in the northeastern United States.
Environmental context
The Claryville station is situated in a forested, rural area of the Catskill Mountains, an ecologically sensitive region that receives significant atmospheric deposition. Monitoring here helps assess the impact of air pollution on sensitive ecosystems, including forests and headwater streams. The site's location is representative of regional background conditions, providing critical data for understanding the transport and transformation of pollutants from urban and industrial sources to the east and west.
Frequently asked questions
The Claryville air monitoring station is located at 47 Southern Way in Ulster County, New York, United States. It is situated in a rural area within the Catskill Mountains.
Claryville is part of the Clean Air Status and Trends Network (CASTNET), which is operated by the U.S. Environmental Protection Agency to monitor the effects of air pollution on ecosystems.
As a CASTNET site, Claryville measures ozone, sulfur dioxide, nitrogen compounds (such as nitric acid and ammonia), and particulate matter. These measurements help assess acid deposition, nutrient pollution, and regional air quality.
CASTNET data is used to evaluate the effectiveness of the Clean Air Act and its amendments, particularly regarding acid rain, ozone, and particulate matter standards. The network provides long-term trends that inform policy decisions and ecosystem protection.
The station's rural location in the Catskills provides background air quality data representative of the northeastern United States. This helps distinguish local pollution sources from regional transport and supports studies on ecosystem impacts.
