  1. Cooperative State Research, Education, and Extension Service Agricultural Ecology Program: Understanding sources and sinks ofnutrients and sediment in the upper Susquehanna River basin Connecticut Hill Atmospheric and Precipitation Chemistry Research and Monitoring Facility Measuring Atmospheric N Inputs Clean Air Status and Trends Network (CASTNet) Site CTH 110 The site is one of the longest operating wet and dry deposition sites in the U.S. Designed to be regionally representative, the 6 ha site is located near the 4500 ha NYS Conn. Hill Game Management Area. Both the landscape and land use are typical of other headwater sections of the Susquehanna River watershed in New York State. Weekly drydepositionincludinggaseous HNO3& particulateNO3- and NH4+ National Atmospheric Deposition Program (NADP/AIRMoN Site NY67) Daily precipitation chemistry for NO3- and NH4+ as well as other ionic species Data to be collected for this project Improve measurement of dry deposition of N, especially gaseous NO2, NH3. At least 1/3 of the measured total N deposition at the sites is in theform of dry deposition, but not all components have been measured yet. MARGA (Monitoring instrument for aerosols and gases; see box at left) hourly sampling for gaseous NH3, HNO3, and HNO2, and particulate NH4+ and NO3-; ThermoElectron 42C-Y chemiluminescence detector for hourly sampling for NOy Passive gas sampler monitoring for dry deposition of NH3, NO2, NOx, HNO3 Comparison of data from passive samplers and CASTNet filter packs Further tests of spatial variability of dry deposition components NOx emissions impacting area MARGA Output (also measures particulate NH4+ and NO3-)
