Abstract

Air pollution kills millions of people each year, indicating pollutant monitoring is essential. This study focuses on concentrations of aerosols, fine particulate matter, and sulfur species in the Lewis-Clark Valley over multiple years. A NASA AERONET Sun‐sky radiometer, an Idaho Department of Environmental Quality beta attenuation monitoring (BAM) PM2.5, and a Teledyne T102 ultraviolet-fluorescence sulfur analyzer were used to obtain ground-based data. Continuous monitoring of these air pollutants will discern long term trends in the area, and help identify main sources emitting these pollutants.
