This project will assess the relationship between a proposed index of aquatic acidification due to airborne pollutants and the concentrations in air of ammonia, ammonium, nitrogen oxides and sulfur oxides. Data comes from participation in both the Ammonia Monitoring Network (AMoN) and EPA's CASTNet. AMoN is a NADP network measuring NH3 concentrations across the United States with the goal of providing long term trends in ambient NH3 concentrations and depositions. The VMC air quality site began participating in this network in November 2012 as a component of the AAI. CASTNET is a national air quality monitoring network designed to provide data to assess trends in air quality, atmospheric deposition, and ecological effects due to changes in air pollutant emissions.CASTNET measurements are used to assess long-term, regional trends in sulfur and nitrogen pollutants.Castnet Filter Pack Weekly ConcentrationsWeekly concentrations of NOx, SOX, Ca, Na, Mg, K and Cl for use in Aquatic Acidification modelVMC.312.411mySQLhttps://vmc.w3.uvm.edu/vmcdevel/CI4/data/archive/project/aquatic-acidification-index-pilot-study-to/dataset/weekly-concentrations2012-11-13SITE_IDSite IDSite identification codetextYEARYearCalendar year of measurement using standard Tuesday to Tuesday weeksdatetimeYYYYWEEKWeekWeek of year as defined by the first Tuesday to Tuesday week of the year intmeterinteger153DATEONDate OnDate and time standard Tuesday to Tuesday period began Local Standard TimedatetimeYYYY-MM-DDThh:mm:ssDATEOFFDate OffDate and time standard Tuesday to Tuesday period ended Local Standard TimedatetimeYYYY-MM-DDThh:mm:ssSO2_CONCSO2 ConcentrationMean ambient sulfur dioxide (SO2) concentrationdecimalmeterrealSO4_CONCSO4 ConcentrationMean ambient particulate sulfate (SO4) concentrationdecimalmeterrealNO3_CONCNO3 ConcentrationMean ambient particulate nitrate (NO3) concentrationdecimalmeterrealHNO3_CONCHNO3 ConcentrationMean ambient nitric acid (HNO3) concentrationdecimalmeterrealTNO3_CONCTNO3 ConcentrationTotal ambient nitrate (NO3+HNO3) concentrationdecimalmeterrealNH4_CONCNH4 ConcentrationMean ambient particulate ammonium (NH4) concentrationdecimalmeterrealCA_CONCCa ConcentrationMean ambient particulate calcium (Ca) concentrationdecimalmeterrealNA_CONCNa ConcentrationMean ambient particulate sodium (Na) concentrationdecimalmeterrealMG_CONCMg ConcentrationMean ambient particulate magnesium (Mg) concentrationdecimalmeterrealK_CONCK ConcentrationMean ambient particulate potassium (K) concentrationdecimalmeterrealCL_CONCCl ConcentrationMean ambient particulate chloride (Cl) concentrationdecimalmeterreal
