Ancillary air pollutant data for PAVA GBNP

As part of this study, several sites were selected for additional instrumentation to help quantify air pollutant composition and identify potential sources of O3. One of these sites was GBNP, and the others were at Paradise Valley (PAVA) in north-central Nevada, and Echo Peak (ECHO) on the Nevada Nuclear Security Site (NNSS) in the south (Fig. 1). Since ancillary air pollutants, aerosols, and mercury (Hg) AZ505 may enter Nevada by way of the free troposphere (Weiss-Penzias et al., 2009, Gustin et al., 2013 and Huang and Gustin, 2012), we hypothesized prey switching these in combination may be applied to understand sources of O3 to Nevada.
