Code Tables used with the High-Resolution CTD/STD format (F022)
0053 CLOUD TYPE (WMO 500)
---- --------------------
0 -- CIRRUS
1 -- CIRROCUMULUS
2 -- CIRROSTRATUS
3 -- ALTOCUMULUS
4 -- ALTOSTRATUS
5 -- NIMBOSTRATUS
6 -- STRATOCUMULUS
7 -- STRATUS
8 -- CUMULUS
9 -- CUMULONIMBUS
X -- CLOUD NOT VISIBLE OWING TO DARKNESS, FOG, DUSTSTORM, SANDSTORM, OR
OTHER ANALOGOUS PHENOMENA
0080 STD-SCAN CONDITION
---- --------------------
0 -- DATA PROCESSED PRIOR TO IMPLEMENTATION OF CODE. ALL VALUES FOR
ALL PARAMETERS WILL BE LABELED THE
SAME.
1 -- VALUE OBTAINED FROM RAW DATA AT THAT DEPTH INTERVAL. PROCESSING
TO OBTAIN THIS VALUE MUST BE
SPECIFIED IN A DDF. EXAMPLE: THE VALUE FOR SALINITY MAY BE THE
RESULT OF AVERAGING OVER ONE METER
INTERVAL AND APPLYING A FIELD CORRECTION BASED UPON DISCRETE
SAMPLES. (OTHER TYPES OF PROCESSING
MAY BE USED, BUT MUST BE SPECIFIED IN DDF.)
2 -- VALUES ARE LINEARLY INTERPOLATED FROM ADJACENT DEPTH INTERVALS.
EXAMPLE: IF THE TEMPERATURE
VALUES FROM 49 AND 50 METERS ARE MISSING, THESE VALUES WILL BE
OBTAINED BY LINEAR INTERPOLATION
BETWEEN THE VALUES AT 48 AND 51 METERS.
3 -- VALUES ARE OBTAINED BY "VERTICAL EXTRAPOLATION" FROM THE FIRST
DEPTHS FOR WHICH A VALUE IS FOUND
THAT FALLS WITHIN SENSOR LIMITS. EXAMPLE: IF SALINITY FALLS
BELOW SENSOR LIMITS BECAUSE OF FRESH
SURFACE WATER, THOSE DEPTHS AFFECTED WILL BE ASSIGNED THE
SALINITY OF THE FIRST REAL VALUE OBTAINED
(SALINITY SENSORS WILL BE AFFECTED TO A MUCH GREATER EXTENT THAN
CONDUCTIVITY SENSORS.)
4 -- AVERAGED
5 -- TEMPERATURE INTERPOLATED
6 -- SALINITY INTERPOLATED
7 -- TEMPERATURE AND SALINITY INTERPOLATED
8 -- OXYGEN INTERPOLATED
9 -- TEMPERATURE, SALINITY, AND SIGMA-T NOT GIVEN
A -- TEMPERATURE AND OXYGEN INTERPOLATED
B -- SALINITY AND OXYGEN INTERPOLATED
C -- TEMPERATURE, SALINITY AND OXYGEN INTERPOLATED
