Abstract

The de Gouw group has a vested interest in the study of air quality in Denver and the northern Front Range of Colorado. In summer 2024, we made measurements of volatile organic compounds and inorganic trace gases at the La Casa ASCENT site in Denver. This poster presents results from three different analyses of this data, all aiming to understand air quality in the region. First, we show results of modeling ozone sensitivity using observationally constrained emissions and the near-explicit Master Chemical Mechanism. Second, we show field measurements of an emerging contaminant, chloramines, and describe laboratory work performed to quantify the field data. Lastly, we use a General Additive Model developed at the University of Washington for analysis and to quantify wildfire emission contribution to ambient ozone concentrations in Denver.
