| Description | Particulate matter mass (PM), trace gaseous pollutants, and select volatile organic compounds (VOCs) with meteorological variables were measured in Logan, Utah (Cache Valley) for > 4 weeks during winter 2017 as part of the Utah Winter Fine Particle Study (UWFPS). Higher PM levels for short time periods and lower ozone $(O_{3}$) levels were present due to meteorological and mountain valley conditions. Nitrogenous pollutants were relatively strongly correlated with PM variables. Diurnal cycles of $NO_{x}$, $O_{3}$ and fine PM $(PM_{2.5}$) suggested formation from nitrogen oxides. $O_{3}$ levels increased from early morning into mid-afternoon, and $NO_{x}$ and $PM_{2.5}$ increased throughout the morning, followed by sharp decreases. Toluene/benzene and xylenes/benzene ratios and VOC correlations with nitrogenous and PM species were indicative of local traffic sources. Wind sector comparisons suggested pollutant levels were lower when winds were from nearby mountains to the east versus winds from northerly or southerly origins. |
