95-m AGL plumes for 333-m configuration. Plume at 95 m above ground level (AGL) from 333-m mesoscale configuration, valid at 1800 UTC (=1300 LST) (left), and after averaging every 10 minutes from 1700–1900 UTC (=1200–1400 LST) (right). Concentration is normalized by $Q/(Uzi2)$⁠, where Q is source strength, U is mean wind speed, and z_i is mixed layer height. Concentration contours are shown in logarithmic intervals with adjacent colors representing a factor of two difference. Horizontal distance is given both in km and in units of x₀ = Uz_i/w_*, where w_* is the convective velocity scale, as defined in text. DOI: https://doi.org/10.1525/elementa.247.f6
