Flight #8
Takeoff: 13:24 CDT
Total flight time: 6.1 hours

Houston urban and ship-channel pollution was released into clean, southerly flow of 4 to 5 m/s, producing transport of the pollution plumes to the north. Sampling legs took place north of the city in approximately west-east flight legs. Data from the first leg, about 20 km north of the sources/urban area, distinguished two ozone and aerosol concentration maxima, one from the urban area of approx. 100 ppb, and the second from the ship channel industrial sources of approx. 120 ppb or more. Cross sections from the second leg showed two less distinct maxima as the plumes appeared to be merging, and the third and fourth legs farther north showed one wider plume, with peak concentrations exceeding 120 ppb. None of the high concentrations was observed in the surface ozone measurement network.
