WAVES Overpass

Today one could say the heat is on when temperatures climed up to the lower 90s with hourly PM 2.5 concentrations in the range of 12.0 to 22.6 μg/m³ as reported at Oldtown. It has remain mostly clear here during the day with a slight haze in the evening. The first of these two plots shows a night time run in which one can see a lowering boundary layer and some clouds showing up around 05:00 UTC (1:00 am). This run was taken in our continued support for GALION, a global aerosol lidar network. The second run is one of the WAVES 2007 Aqua overpasses. One can see here the growing boundary layer from 1.5 to 2.5 km.

Readers note: the two plots are shown with different color scales to show features.
