After TOPAZ maintenance in the morning, data were taken from 12:27 - 18:51 PDT. High pressure in control, hot (36 C max), light to moderate winds, isolated Cu clouds over the nearby mountains. The MicroDop lidar observed intermittent turbulence at night. The convective daytime BL rose to about 2.5 km AGL in the afternoon. Surface ozone stayed somewhat elevated (25-45 ppbv) overnight and increased to the low 60s ppbv in the afternoon. TOPAZ observed high ozone above 4.5 km AGL (75 - 90 ppbv).
