Averaged mixing ratios (ppbv) of selected VOC at six sites during the diffusive sampling survey of February 14–17 2012.
Data from the WDEQ Boulder monitoring site and a roadside site in downtown Pinedale are presented with remaining four sites that correspond to those with high BTEX and NOx mixing ratios, identified by the plots in Figure 4 (see text).
