  • Passive ammonia monitoring in the United States: Comparing

    Description: The need for ambient gaseous ammonia (NH3) measurements has increased in the last decade as reactive nitrogen concentrations and deposition fluxes show little change even with tightening standards on nitrogen oxides (NOx) emissions. Currently, there are several networks developing methods for adding NH3 measurements in the U.S. Gaseous NH3 measurements will provide scientists and policymakers data which can be used to estimate ecosystem inputs, validate air quality models
