Data summary 12/04 06Z through 12/05 10Z

SURFACE DATA: Generally good. 


SOUNDING - PROFILER COMPARISON:

RASS good. Parallel to and warmer than sonde.

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

12/04 21Z (1944): Speed: within 2-3 m/s (both modes) throughout.
		  Direction: Good (both modes) < 20 deg. except near 200m.
		  where sounding direction is off.
12/05 00Z (2300): Speed: Within 2-3 m/s above 500m (both modes).
		  Direction: Good at times above 1000m.
12/05 02Z (0200): Speed: Within 2-4 m/s above 500m (both modes).
		  Direction: Poor - sounding data at low levels are bad.
12/05 06Z (0605): Speed: Within 2-4 m/s above 500m (both modes).
		  Direction: Poor - sounding data at low levels are noisy.


PROFILER DATA:

Low mode: typically to 1.5 to 2.5 km. 
High mode: typically to 2.0 to 3.0 km. 
RASS: profiles today: 400-1200m.

SOUNDING COMMENTS:

12/04 06Z (0532): Sonde T,Td values high prior to launch (in launcher);
12/04 09Z (0753): Sonde T,Td values high prior to launch (in launcher);
                  Wind data missing/questionable throughout sounding.
12/04 12Z (1102): Good sounding.
12/04 15Z (1355): Noisy PTU data (will cleanup in post processing),
		  Data ends at 300mb.
12/04 18Z (1656): Some noise in PTU data (will cleanup in post processing),
                  otherwise good sounding.
12/04 21Z (1944): Good sounding.
12/05 00Z (2300): Sonde T,Td values high prior to launch,
                  otherwise, good sounding.
12/05 02Z (0200): Sonde T,Td values high prior to launch, wind data at low
		  levels questionable.
12/05 06Z (0605): Sonde T,Td values high prior to launch, wind data at low 
                  levels questionable.


SITE LOG INFORMATION: 

SHIP POSITION BASED ON LAST SOUNDING: 41.38 S  138.619 E

Data summary 12/04 15Z through 12/05 15Z

SURFACE DATA:

All sensors look good. 


SOUNDING - PROFILER WIND COMPARISON:

RASS - Sounding temperature comparison is good.

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

12/04 12Z (1100): Speed within 2 m/s above 800m (both modes).
		  Direction: within 10-20 deg throughout.
12/05 00Z (2252): Speed within 2-4 m/s (both modes) except near 900m.
		  where sounding data appears bad.
		  Direction: good agreement within 10-20 deg. throughout.
12/05 06Z (0500): Sounding data is intermittant/bad thus poor 
		  comparison. Profiler data likely fine.
12/05 18Z (1100): Speed within 2-4 m/s overall with periods of
		  bad sounding data (both modes).
		  Direction: Some agreement < 20-40 deg. at times.


PROFILER DATA:

Low mode: 2.5 to 4.0 km. 
High mode: 3.0 to 4.5 km.
RASS: profiles generally 500-1200 m.

SOUNDING COMMENTS:

12/04 12Z (1100): Some sensor arm heating at launch. Otherwise good data.
		  Some missing data (wind and PTU) for a brief period near 
		  550mb.
12/04 18Z (    ): No sounding.
12/05 00Z (2252): Some sensor arm heating at launch. Otherwise good data.
12/05 06Z (0500): Sensor arm heating at launch. Noisy PTU below 600mb (will
		  cleanup in post processing). Little wind data. Some of
		  that questionable.
12/05 12Z (1100): Noisy PTU data at times, much of wind data questionable.
