Data summary 12/08 18Z through 12/11 14Z

SURFACE DATA: Generally good. 


SOUNDING - PROFILER COMPARISON:

RASS parallel to and warmer (1.0 deg.) than sonde.

Comparison of low and high mode profiler wind speed and direction 
to that of CLASS sounding.

12/11 00Z (2259): Speed: Within 2-4 m/s throughout.
		  Direction: within 10-20 deg. above 500m (both modes).
12/11 03Z (0211): Speed: Within 2-3 m/s above 1000m (low mode).
		  Speed: Within 2-3 m/s above 1500m (high mode).
		  Direction: within 10-20 deg. throughout (both modes).
12/11 06Z (0455): Speed: within 2-4 m/s above 1000m (both modes).
		  Direction: within 10-20 deg. between 1-2 km (both modes).
		  Within 40 deg above 2km - some oscillation in Omega data.
12/11 12Z (1103): Speed: Profilers 2-3 m/s throughout (both modes).
		  Direction: within 20-30 deg. throughout (both modes).


PROFILER DATA:

(Most recent 24 hours.)
Low mode: typically to 2.5 to 4.0 km. 
High mode: typically to 3.0 to 6.0 km. 
RASS: profiles today: 600-1000m.

SOUNDING COMMENTS:

12/08 21Z (1958): Good sounding. Cloud penetration just below 800mb?
12/09 00Z (2257): Sonde T,Td values slightly high prior to launch,
                  otherwise, good sounding.
12/09 03Z (0200): Good sounding.
12/09 06Z (0459): Sonde T,Td values high prior to launch; Some noise in
                  PTU data (will cleanup in post processing).
12/09 12Z (1110): Good sounding.
12/09 18Z (1700): Sonde T,Td values high prior to launch; Some noise in
                  PTU data (will cleanup in post processing).
12/10 00Z (2300): Some noise in PTU data (will cleanup in post processing)
                  Otherwise, good sounding.
12/10 06Z (0458): Sonde T,Td values high prior to launch; Winds below 900mb
		  are suspect.
12/10 12Z (1104): Good sounding.
12/10 18Z (1707): Good sounding.
12/11 00Z (2259): Sonde T,Td values high prior to launch.
                  Otherwise, good sounding.
12/11 03Z (0211): Sonde T,Td values high prior to launch. Otherwise, good
                  sounding.
12/11 06Z (0455): Sonde T,Td values high prior to launch. Otherwise, good
		  sounding.
12/11 12Z (1103): Good sounding.


SITE LOG INFORMATION: 

SHIP POSITION BASED ON LAST SOUNDING: 44.94 S  144.756 E  (17Z 12/11)
SHIP IS DUE IN PORT AT HOBART EARLY MORNING WEDNESDAY DEC. 13.
