Depiction of the vertical levels used in the four different large-scale models and the regional CMAQ model analyzed in this study. The pressure values were extracted for a location near the southwestern corner of the 12 km CMAQ modeling domain and represent annual average values for 2010 at the midpoint of each vertical level. The dashed lines delineate the three pressure ranges (surface to 750, 750–250, and 250–50 mb) used for vertical integration in subsequent analyses.
