Code Tables ACT_CODE (Parameter action code) CodeMeaning CF Change a quality flag CR Create record CT Constant temperature, hit bottom. The temperature profile exhibits constant temperature which is considered to be erroneous when compared to neighbouring profiles and/or climatology and/or known characteristics of the region. The constant temperatures could occur over all of the profile or part of it. (The reasons could be sensor failure, depth calculation error, nose falling off the XBT, XBT sitting on the bottom, etc.) CV Change value DC Station was checked by duplicate checking software ED Edit a parameter value FS Fine structure error: leakage, PET fault, cusping, sticking bit. The temperature profile exhibits erroneous fine structure when compared to neighbouring profiles and/or climatology and/or known characteristics of the region. (The reasons could be signal leakage, XBT recording system failures (sticking bit, cusping, PET Fault, etc), complete instrument failure, etc) IP This history group operates on the complete input record ML Mixed layer error: bowing. The temperature profile exhibits erroneous features (such as false inversions) in the mixed layer when compared to neighbouring profiles and/or climatology and/or known characteristics of the region. (The reasons could be XBT bowing problem, instrument drift, etc). NG No good trace PE Position error. Profile position has been erroneously encoded. Corrected if possible. QC Quality Control SF Surface feature error: surface anomaly, chopped surface value. The temperature exhibits erroneous features at the surface when compared to neighbouring profiles and known characteristics of the region. (The reasons could be XBT start-up transients, general instrument equilibration problems, sensors recording prematurely before entering water, etc) SV Set a value TE Time error. Profile date/time has been erroneously encoded. Corrected if possible. TG Temperature gradient error: insulation penetration, spikes, high frequency noise, wire break, modulo 10 spikes. The temperature profile exhibits erroneous temperature gradients when compared to neighbouring profiles and/or climatology and/or known characteristics of the region. (The reasons could be spiking, interference, XBT wire break, modulo 10 problem, XBT wire insulation penetration, etc) TI Temperature inversion error: wire stretch. The temperature profile exhibits erroneous temperature inversions when compared to neighbouring profiles and/or climatology and/or known characteristics of the region. (The reasons could be XBT wire stretch, sensor drift, encoding error, etc). TO Temperature/depth offset. The temperature profile exhibits erroneous temperature/depth offsets compared to neighbouring profiles and/or climatology and/or known characteristics of the region. The offsets can occur.at depth, or over sections of the profile, or over the complete profile (The reason could be instrument drift/sensor failure, encoding error, XBT fall rate error, XBT start-of-descent timing error, etc) UP Station passed through the update program UR Under resolved. Temperature data is encoded at standard depths/levels and can't be used to reconstitute a profile accurately. ------------------------------------------------------------------------ AVAIL (Availability) CodeMeaning A Available P Protected ------------------------------------------------------------------------ BUFR SST Method CodeMeaning 00 Ship intake 01 Bucket 02 Hull contact sensor 03 Reversing thermometer 04 STD/CTD sensor 05 Mechanical BT 06 Expendable BT 08 Thermistor chain 09 Infrared sensor 10 Microwave sensor ------------------------------------------------------------------------ DATA_TYPE CodeMeaning BA BATHY BO Bottle CD CTD down cast CU CTD up cast CT CTD up or down cast DB DRIFTER MB MBT PF Profiling ALACE float TE TESAC TK TRACKOB TR THERMISTOR CHAIN (delayed mode) XB XBT ------------------------------------------------------------------------ DIGIT_CODE (Digitization Method) CodeMeaning 0 Unknown method 7 Digitized at regular depths (e.g. every 5 meters) 8 Digitized at profile inflexion points D Digital data logger, unreduced ------------------------------------------------------------------------ D_P_CODE (Depth / pressure code) CodeMeaning D Independent parameter is Depth P Independent parameter is Pressure ------------------------------------------------------------------------ IDENT_CODE (Organization code) CodeMeaning AD Australian Oceanographic Data Centre AO Atlantic Oceanographic & Meteorological Laboratory (U.S.) CS Commonwealth Scientific & Industrial Research Organization (Australia) FN Fleet Numerical Oceanography Center (U.S.) GE Bundesamt fur Seeschiffahrt und Hydrographie (Germany) JA Japan Meteorological Agency (Japan) ME Marine Environmental Data Service (Canada) NO National Oceanographic Data Center (U.S.) NW National Weather Service (U.S.) SI Scripps Institution of Oceanography (U.S.) TS TOGA Subsurface Data Centre (France) ------------------------------------------------------------------------ PCODE (either GF3 or GTSPP codes) CodeMeaning Units ACCSAccession number ADIDAODC Unique ID ATMSAtmosperic pressure at sea level hectoPascals BATHBathymetric Depth meters BCI$Indicator for Method of Current WMO Code 2266 Measurement BMS$BUFR SST Method Code see BUFR SST Method table above CLDATotal Cloud Amount WMO Code 2700 CLDTCloud Type WMO Code 0500 CSIDCSIRO unique ID DBIDNODC Database Identification Number NODC Code (Unique Identifier) DEWTDew Point Temperature degrees C DRDPDepth of drogue meters DRYTDry Bulb Temperature degrees C FRQ$Argos system data (frequency) used for back conversion to Raw data GCLLCall Sign NODC Code GGCMIndicator for Method of Current WMO Code 2266 Measurement GNCONODC consecutive station number GNCRNODC Cruise Number NODC Code GNOXPosition 1 = OSV Flag NODC Code Position 2 = Instrument Type Position 3 = Probe Type GOCOOriginators Consec Number NODC Code GOCROriginators Cruise Number NODC Code ICEFFlag for Ice in vicinity of Hydrographic ICES Code Observation IDENData identifier LDATLoad Date at NODC LNC$Launcher height meters PDIDNODC Ocean profile database ID PEQ$XBT fall rate equation WMO code 1770 PFR$XBT probe type and fall rate equation WMO code 1770 and 4770 PGIDProgram identification PLATPlatform NODC Code PRHBProbe Hit Bottom Indicator GF3 Code (0 = no, 1 = yes) PROJNODC project code PRT$XBT probe type PSALSalinity PSU QAF$QC tests "Fail" -
