Daily Summary:

Saturday, June 24
TOPAZ data were recorded from 09:45 - 21:13 PDT. Another extremely hot day (max. of 45 C at the lidar site) and 111 F at the NLVA NWS tower. Mostly clear with scattered high clouds and some cumulus development to the SW and over the mountains. Calm or very light winds all day. The elevated aerosol and ozone layer from the AZ and Mexican fires was present once again between 4 and 6 km asl, but was only weakly entrained by the relatively shallow mixed layer. Ozone production was modest with peak concentrations of 65 ppbv, despite very similar conditions as yesterday when surface ozone reached 100 ppbv. This Friday-Saturday combination could be a good candidate for a modeling study.
