• Flight 7:12-14:35UTC
• High-altitude transit for HSRL
• Found somewhat broken clouds at ~7.5S. 
• Radiation wall module components:
  
  • Spiral in somewhat heavier cloud field.
  • Ramped ascent south-bound to just above cloud.
  • Above, below, then sawtooth in-cloud 2-sawtooth leg. Chose sawtooth to capture variability in microphysics.

{AMS, CCN compromised below 3000’ altitude by PTI leak up until end of cloud legs}

Transited on 5E to 9.0S, then headed east to find low-cloud-fraction region. At ~7E went south to 9.5S, then headed west. 
Did a radiation wall between approx. 5.5E and 7W on 9.5S. This included, in order:

This was a target of opportunity flight to: a) resample boundary layer air first sampled on PRF#07, and b) sample cloud properties across aerosol boundaries.

routine flight to 13S. high-altitude transit to 13S, followed by in-situ sampling on the way back that included three samples of the cloudy boundary layer, at 13S, ~8.5-7.5S, and 3.5S. boundary layer was mildly polluted. aerosol layer at southern end reached 19.5 kft. flight included speed runs for the cloud probes (the 2 CDP probes in particular).
