Ammonia (NH3) concentrations, WIND SPEED, and others collected at the Yale Coastal Field Station (YCFS) in Guilford, CT from 20230427 to 20231024 (NCEI Accession 0314162)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 05:22 AM | Dataset Last Updated: April 23, 2026 at 12:00 AM
In collaboration with Yale University, scientists and engineers from NOAA conducted ground-based atmospheric NH3 concentration measurements from April 27 to October 24, 2023. In this field study, continuous and high-temporal resolution measurements of atmospheric NH3 concentrations and meteorological variables were collected at the Yale Coastal Field Station (YCFS) in Guilford, CT as part of the Atmospheric Emissions and Reactions Observed from Megacities to Marine Area (AEROMMA) campaign. The objectives of this study were to characterize the magnitude and the seasonal variability of atmospheric NH3 concentrations, as well as to evaluate the effect of wind direction in order to analyze the influence of emission sources of NH3 upwind at the YCFS located in the Long Island Sound region, which often experiences poor air quality.
