We are again in a period with baseline conditions, CN around 500 cm-3 and 
CCN @ 0.5% around 100 cm-3.  
The Grim TSI 3760 CN counter was repaired yesterday and is
functioning well again.
Winds are currently around WSW at 7m/s.

The particle size distribution is "typical" maritime - with modes at 
around 30 nm and 100 nm diam.

When the time comes for sorting out remaining flight priorities we'd like 
the case for an boundarylayer strucure/entrainment study off Cape Grim when 
the winds are in the SW "baseline" sector.  I have forwarded the Generic 
Flight Plan suggested by RB to Jorgen.
