FAST-LVOS 2017 TOPAZ Data
June 13, 2017
Tuesday, June 13
TOPAZ data were recorded from 6:44 - 21:00 PDT. These measurements were a continuation of the long time series that started at 0800 PDT on June 11. Warming temperatures (max. of 34 C), clear conditions, and light to moderate winds from the NW. Highly structured ozone aloft with multiple thin layers associated with yesterday's intrusion. High ozone descended to below 3 km agl around midday, but the mixed layer only reached about 2200 m agl and was too shallow to entrain much of it. The surface concentrations reached about 65 ppbv during the afternoon with similar concentrations at the CC monitors.
