The WOCE American Standard Code for Information Interchange (ASCII) manual for quality controlled (QC) surface meteorological data outlines the codes used within the DAC surface meteorological data sets released to the WOCE community. The code is a synthesis of the COADS documentation (Slutz et al. 1985), standard World Meteorological Organization (WMO) synoptic code, and new codes derived at Florida State University (FSU). In many places numeric codes were used to keep the data set compact.

The WOCE ASCII data file includes up to 31 possible parameters. In some cases, multiple measurements of the same parameter are available (e.g. sea temperature measured from a thermosalinograph and a bucket temperature) and are differentiated using sequentially numbered variable names (TS, TS2, TS3, TS4, etc). As described in section 2, variables include not only meteorological data (temperature, pressure, etc.), but also a number of supporting variables (time of observation, platform position and movement, etc.). A variable containing quality control (QC) flags is included to indicate the QC applied to the data values. Multiple variable attributes provide information on data units, instruments used, instrument height, etc. in an attempt to provide an even mix between raw data and metadata. Thirteen global attributes contain general information for all data within the ASCII file.

When the data arrive at the Surface Meteorology DAC, the only change to the data is a simple conversion to a standard set of units. The original units are noted in a variable attribute. Any data arriving without an accurate time stamp or information on whether the time is local or UTC were discarded only after all attempts to obtain correct time information were exhausted. The data also must have position information, i.e. data lacking latitude and longitude values were discarded only after all attempts to correctly position the data failed. Furthermore, if data arrived with no units attached, only after every effort to determine their units was exhausted, were the data discarded. Data collected without a record of time, position, or units are useless to the research community. However, all original data contributions are archived in the event additional information is discovered later that would allow the inclusion of discarded data.

The ASCII file Appendix 1 contains 3 parts, a multi-line header containing metadata information, a multi-line discription of the Quality Control Flags, and the data in columnar format. The first line of the header contains the NetCDF file name used to create the ASCII file followed by a blank line. The next 17 lines contain the file's global attributes followed by another blank line. The third section of the the header (next 21 lines) contains a summarized description of the QC flags in use as of the date the ASCII file was created. The fourth section of the header contains a table giving the values for the variable attributes. The length of this table is determined by the number of variables in the file. The data section follows after a blank line and a line of column titles for each data type.

The DAC has now expanded beyond the WOCE parameters to provide other useful cruise data to researchers. These (non-woce;RVSMDC) cruises are set up in very much the same way as WOCE cruises, but are not resricted to the same time and location constraints. Many of the RVSMDC cruises are infact the same ships that provide WOCE data, but just at different times. One of the main differences between WOCE and RVSMDC data are the longitude convention. At the request of the WOCE Data Committee, all WOCE ASCII files (version 300) contain longitude units in the (+E/-W) 180 degrees convention. The RVSMDC standard longitude units are from 0-359.99 degrees East. All data that are not included in WOCE have the 0-359.99 degrees East units convention.

Section 2 outlines the data variables and attributes and describes all numeric codes that are employed. Section 3 covers the global attributes. Throughout the manual, variables will be indicated by bold type and attributes will be italicized.

Up to 31 parameters may appear in a surface meteorology file for WOCE, Table 1. All data files will contain the time, latitude, longitude, and quality control flag variables. The quality control flags are single alphabetic characters that represent either problems or notable features in the data. The quality control flags for multiple variables are combined in a single string and stored in the flag variable. The flag variable as a result is a character string that has a length equal to the number of variables that underwent quality control (a list of the flags, their definitions, and an example of their usage is found in section 2bb). For each variable, Table 1 shows whether or not that attribute is associated with a particular variable.

**At the request of the WOCE Data Committee, all WOCE files (version 300) contain longitude units in the (+E/-W) 180 degrees convention. An example of the WOCE ASCII file is located in Appendix 1. The RVSMDC standard longitude units are from 0-359.99 degrees East. All data that are not included in WOCE have the 0-359.99 degrees East units convention.

The definition of the attributes are:

• long_name: A descriptive name for the variable which is given in Table 1.
  
• units: The SI units used for the variable values. Since no data are useful without units, this attribute will always have a value (when units: is applicable). Units are given for most variables in Table 1. The exception are those variables that are coded (ctc, WX, etc.) which refer to the specific code table.
  
• convers_units: The units (SI, English, cgs, etc.) of the variable value when it arrived at the DAC. Again, since no data are useful without units, this attribute will always have a value when present. If a variable has convers_units:, Table 1 references specific code tables for the convers_units:.
  
• type: A coded attribute that signifies the variable value as being a certain type. For example, type: indicates if the pressure is station level or converted to sea level. Code tables for type: are referenced in Table 1
  
• instrument: A character attribute that contains the make, model number, manufacturer and/or type of instrument used to record the variable values. When no information on the instrument type is known, instrument: = "unknown". Table 1 lists whether or not an instrument: attribute exists for each variable.
  
• height: The instrument height in meters above the station elevation (see Global Attributes, section 3). When unknown, height: = -999.9. Table 1 lists whether or not a height: attribute exists for a variable. NOTE: the height attribute for sea temperature is named "depth: "and is a positive number in meters below sea level.
  
• FORTRAN_format: A FORTRAN specific format for printing each variable. The formats for ctc, time, woce_date, woce_time_of_day, WX, TCA, LMCA, ZCL, LCT, MCT, and HCT are a fixed length. The length of the flag FORTRAN_format: varies depending on the number of variables that were quality controlled in the netCDF file. All floating point values are represented by F9.n where n indicates the decimal precision of the supplied data. The formats provided in Table 1 show the maximum precision a variable can have within the WOCE netCDF file. As an example, latitude and longitude have a FORTRAN_format: of F9.2 in Table 1. If the position data we receive is accurate to two decimal places, the FORTRAN_format: will remain F9.2. If the position data is only accurate to the tenths place the FORTRAN: _format: will be F9.1 and for data accurate to the whole number the FORTRAN_format: will be F9.0.
• qcindex: An integer pointer to the flag for the selected variable. Table 1 lists which variables have a qcindex.

a) Cruise track code (cruise_track_code)

The cruise track code stores up to a 9 character string that marks each recording time as being either a WOCE cruise, another dedicated cruise (other), or a cruise with an 'unknown' designation. A WOCE cruise_track_code will include the WOCE Hydrographic Program transect line number and a sequential cruise number using the format BRS##D/## where:

• B: basin (P - Pacific, A - Atlantic, I - Indian, and S - Southern)
  
• R: repeat cruise ( if not a repeat, an '_' will occur here)
  
• S: time series cruise ( if not a time series, an '_' will occur here)
  
• ##: WHP line number
  
• D: portion of cruise line (E - east, N - north, W - west, S -south, C - central) where applicable (if not used, an '_' will occur here)
  
• /##: repeat cruise number (all repeat and time series cruises will have a number starting from 01. All one time cruises are labeled 00, unless a one time cruise line is completed in several legs, then cruise numbers starting at 01 are given) - in all cases the numbers are sequential based on the date when a cruise became known to the DAC, with the smallest number being the oldest data. The repeat cruise # is unique for each WHP line; however, some gaps in the numbering sequence do exist (e.g., when a planned WHP line was deleted from our archive).
  

For example, the code PRS14E/17 represents the 17th cruise on the Eastern portion of the Pacific Repeat time Series line number 14.

b) Date (woce_date)

The woce_date contains a four digit year (YYYY), two digit month (MM), and two digit date (DD) for each data record. The woce_date is stored as an integer with a format YYYYMMDD and units in the Universal Time Coordinate (UTC). Note: additional information about the data recording times are located in the variable attributes for time (see below).

c) Time of day (woce_time_of_day)

The woce_time_of_day contains the hour (HH), minute (MM), and seconds (SS.SS) for each data record. The woce_time_of_day is stored as a floating point values of the form HHMMSS.SS and units in the Universal Time Coordinate (UTC). Note: additional information about the data recording times are located in the variable attributes for time (see below).

d) time

The time is a double precision variable with units equal to minutes since 1-1-1980 00:00 UTC. We chose 1980 as our reference year primarily because it is the beginning of the decade that is nearest the start of the WOCE data collection. The time is quality controlled for non-sequential and unrealistic values. The type is encoded according to Table 2.

Table 2: Time types.

code definition

• 0: unknown time type
  
• 1: mean time (Data represent a mean observed/recorded over some period of time. Note: prior to 30 March 1996 the position of the recorded time stamp within the mean (e.g. beginning, end, or middle of mean) and the length of the averaging period will be provided in the data quality reports).
  
• 2: instantaneous time (Data are recorded as instantaneous values at the time indicated)
  

Two other attributes, ave_period and ave_center, were added to files after 30 March 1996 to add detail to mean times. The ave_period will contain the length of the averaging period in seconds or have a value of zero when the ave_period is unknown or N/A.

The codes for the ave_center are:

code definition

• 0: unknown, N/A
  
• 1: time stamp at start of averaging period
  
• 2: time stamp at center of averaging period
  
• 3: time stamp at end of averaging period

The time will be quality controlled primarily for non-sequential and duplicate time values and the QC flag index will be stored in qcindex.

A FORTRAN subroutine to convert from minutes since 1-1-1980 00:00 UTC to year, month, day, hour, and minute values is provided in Appendix 2.

e) latitude (latitude)
f) longitude (longitude)

Platform position is in units of degrees; positive degrees for north latitude, negative degrees for south latitude, positive 0-359.99 degrees east longitude for all RVSMDC cruises, and (+E/-W) 180 degrees longitude for all WOCE cruises. The units of the original values of latitude and longitude are found in Table 3.

Table 3: Units of original latitude and longitude.

code definition

• 0: degrees and tenths
  
• 1: whole degrees
• 2: non-random tenths
• 3: interpolated
  
• 4: degrees and minutes
• 5: high resolution data (e.g., degrees to seconds, or degrees and hundredths)
• 6: other (refer to supplemental data)

The latitude and longitude are quality controlled for data validity, unrealistic platform movement, and whether an oceanographic platform moves over land.

g) platform heading (PL_HD)

The heading is recorded in units of degrees (recorded clockwise relative to true north) and represents the direction that the bow of the ship is pointing. Valid headings range from 000.0 to 359.9 degrees. A convers_units attribute stores the original format of compass values using the codes found below in Table 4.

h) platform course (PL_CRS)

The course is recorded in units of degrees (recorded clockwise relative to true north) and represents the direction that the ship is moving relative to the fixed earth. Valid course values range from 000.0 to 359.9 degrees. A convers_units attribute stores the original method of recording the course using the codes in Table 4.

i) platform speed (PL_SPD)

The platform speed is recorded in units of meter per second after a conversion from the original units (encoded using Table 5). Often multiple values are present including, but not limited to, a speed relative to the water (doppler log, etc.) and a speed relative to the earth (gps).

j) earth-relative wind direction (DIR)

The earth-relative wind direction is stored with units of degrees and is encoded using
000.0 = calm
001.0-360.0 = direction in degrees
361.0 = variable (rarely used in bridge data only)
going clockwise from true north. All wind directions are reported in the standard meteorological convention; the direction the wind is blowing from. Table 4 lists the possible compass types used to record the original data.

NOTE: TRUE WIND SPEED AND DIRECTION ARE EITHER CALCULATED BY THE DATA PROVIDER AND CHECKED BY THE DAC, OR THEY ARE CALCULATED BY THE DAC. A comment in the instrument attribute will be included.

NOTE 2: FILES RELEASED AFTER 19 AUGUST 1997 MAY CONTAIN PLATFORM RELATIVE WIND DIRECTION (PL_WDIR) AND SPEED (PL_WSPD). These variables are necessary when assessing errors caused by flow over the vessel or the vessel's acceleration. PL_WDIR and PL_WSPD data for cruises released before 19 August 1997 are available upon request. All coding and units for PL_WDIR and PL_WSPD are the same as DIR and SPD, with the exception that the PL_WDIR is referenced to a zero line on the vessel. This zero_line_ref is included as a variable attribute and coded:

v) total cloud amount (TCA)
w) low/middle cloud amount (LMCA)

The codes for the total and low/middle cloud amounts (Table 15) are from the COADS data (Slutz et al. 1985). For the total cloud amount, codes 0 to 9 show the fraction, in oktas, of the celestial dome covered by all clouds. For the low/middle cloud amount the codes show the fraction, in oktas, of the celestial dome covered by all the low clouds and, if no low clouds are present, the fraction covered by all the middle clouds.

Table 15: Cloud amount codes.

Code Definition

• 0: clear
  
• 1: 1 okta or less, but not zero.
  
• 2-6: 2-6 oktas.
  
• 7: 7 oktas or more, but not 8 oktas.
  
• 8: 8 oktas.
  
• 9: sky obscured or cloud amount cannot be estimated.

If the data arriving at the DAC use tenths to describe cloud cover, the convention in Table 16 will be used to convert from tenths to oktas and the original data units will be noted using the codes in Table 17.

Table 16: Relationship between tenths and oktas.

y) low cloud type (LCT)

Table 19: Low cloud type codes extracted from the COADS data documentation (Slutz et al. 1985). The codes show observed characteristics of clouds of the types stratocumulus, stratus, cumulus, cumulonimbus, and their variations.

Code Definition

• 0: no stratocumulus, stratus, cumulus, or cumulonimbus.
  
• 1: cumulus with little vertical extent and seemingly flattened, or ragged cumulus other than of bad weather, or both.
  
• 2: cumulus of moderate or strong vertical extent, generally with protuberances in the form of domes or towers, either accompanied or not by other cumulus or by stratocumulus, all having their base at the same level.
  
• 3: cumulonimbus the summits of which, at least partially, lack sharp outlines but are neither clearly fibrous (cirriform) nor in the form of an anvil; cumulus, stratocumulus, or stratus may also be present.
  
• 4: stratocumulus formed by the spreading out of cumulus; cumulus may also be present.
  
• 5: stratocumulus not resulting from the spreading out of cumulus.
  
• 6: stratus in a more or less continuous sheet or layer, or in ragged shreds, or both, but no stratus fractus of bad weather.
  
• 7: stratus fractus of bad weather (generally existing during precipitation and a short time before and after) or cumulus fractus of bad weather, or both (pannus), usually below altostratus or nimbostratus.
  
• 8: cumulus and stratocumulus other than that formed from the spreading out of cumulus; the base of the cumulus is at a different level from that of the stratocumulus.
  
• 9: cumulonimbus, the upper part of which is clearly fibrous (cirriform), often in the form of an anvil; either accompanied or not by cumulonimbus without anvil or fibrous upper part, by cumulus, stratocumulus, stratus, or pannus.
  
• 10: low clouds not visible, owing to darkness, fog, blowing dust or sand, or other similar phenomena.

z) middle cloud type (MCT)

Table 20: Middle cloud type codes extracted from the COADS data documentation (Slutz et al. 1985). The codes show observed characteristics of clouds of the types altocumulus, altostratus, and nimbostratus.

Code Definition

• 0: no altocumulus, altostratus, or nimbostratus.
  
• 1: altostratus, the greater part of which is semi-transparent; through this part the sun or moon may be weakly visible, as through ground glass.
  
• 2: altostratus, the greater part of which is sufficiently dense to hide the sun or moon, or nimbostratus.
  
• 3: altocumulus, the greater part of which is semi-transparent; the various elements of the cloud change only slowly and are all at a single level.
  
• 4: patches (often in the form of almonds or fishes) of altocumulus, the greater part of which is semi-transparent; the clouds occur at one or more levels and the elements are continually changing in appearance.
  
• 5: semi-transparent altocumulus in bands, or altocumulus in one or more fairly continuous layers (semi-transparent or opaque), progressively invading the sky; these altocumulus clouds generally thicken as a whole.
  
• 6: altocumulus resulting from the spreading out of cumulus (or cumulonimbus).
  
• 7: altocumulus in two or more layers, usually opaque in places, and not progressively invading the sky; or opaque layer of altocumulus, not progressively invading the sky; or altocumulus together with altostratus or nimbostratus.
  
• 8: altocumulus with sproutings in the form of small towers or battlements; or altocumulus having the appearance of cumuliform tufts.
  
• 9: altocumulus of a chaotic sky, generally at several levels.
  
• 10: middle clouds not visible, owing to darkness, fog, blowing dust or sand, or other similar phenomena, or more often because of the presence of a continuous layer of lower clouds.

aa) high cloud type (HCT)

Table 21: High cloud type codes extracted from the COADS data documentation (Slutz et al. 1985). The codes show observed characteristics of clouds of the types cirrus, cirrocumulus and cirrostratus.

Code Definition

• 0: no cirrus, cirrocumulus or cirrostratus.
  
• 1: cirrus in the form of filaments, strands, or hooks, not progressively invading the sky.
  
• 2: dense cirrus, in patches or entangled sheaves, which usually do not increase and sometimes seem to be the remains of the upper part of a cumulonimbus, or cirrus with sproutings in the form of small turrets or battlements, or cirrus having the appearance of cumuliform tufts.
  
• 3: dense cirrus, often in the form of an anvil, being the remains of the upper parts of cumulonimbus.
  
• 4: cirrus in the form of hooks or of filaments, or both, progressively invading the sky; they generally become denser as a whole.
  
• 5: cirrus (often in bands converging towards one point or two opposite points of the horizon) and cirrostratus, or cirrostratus alone; in either case, they are progressively invading the sky, and generally growing denser as a whole, but the continuous veil does not reach 45 degrees above the horizon.
  
• 6: cirrus (often in bands converging towards one point or two opposite points of the horizon) and cirrostratus, or cirrostratus alone; in either case, they are progressively invading the sky, and generally growing denser as a whole; the continuous veil extends more than 45 degrees above the horizon, without the sky being totally covered.
  
• 7: veil of cirrostratus covering the celestial dome.
  
• 8: cirrostratus not progressively invading the sky and not completely covering the celestial dome.
  
• 9: cirrocumulus alone, or cirrocumulus accompanied by cirrus or cirrostratus, or both, but cirrocumulus is predominant.
  
• 10: high clouds not visible, owing to darkness, fog, blowing dust or sand, or other similar phenomena, or more often because of the presence of a continuous layer of lower clouds.
  

bb) quality control flags (flag)

The quality control flags (Table 22) are single alphabetic characters for each data value. Only those variables with a qcindex have flag values (the qcindex is an integer pointer to the flag for a selected variable), i.e. not all meteorological variables are quality controlled.

Table 22: Definitions of WOCE quality control flags.

Flag Definition

• A: Original data had unknown units. The units shown were determined usuing a climatology or some other method.
  
• B: Original data were out of the range bounds outlined (Table23).
  
• C: Time data are not sequential or date/time not valid.
  
• D: Data failed T>=Tw>=Td test. In the free atmosphere, the value of the temperature is always greater than or equal to the wet-bulb temperature, which in turn is always greater than or equal to the dew point temperature.
  
• E: Data failed resultant wind recomputation check. When the dataset includes the platform's heading, course, and speed along with the platform relative wind speed and direction, a program recomputes the earth relative wind speed and direction and compares the computed values to the reported earth relative wind speed and direction. A failed test occurs when the wind direction difference is > 20 degrees or the wind speed difference is >2.5m/s.
  
• F: Platform velocity unrealistic. Determined by analyzing latitude and longitude positions as well as reported platform speed data.
  
• G: Data are greater than 4 standard deviations from the COADS climatological means (da Silva et al. 1994). The test is only applied to pressure, temperature, sea temperature, relative humidity, and wind speed data.
  
• H: Discontinuity found in data
  
• I: Interesting feature found in data. More specific information on the feature is contained in the data reports. Examples include: hurricanes passing station, sharp sea water temperature gradients, strong convective events, etc.
  
• J: Data are of poor quality by visual inspection, DO NOT USE.
  
• K: Data suspect/use with caution - this flag applies when the data look to have obvious errors, but no specific reason for the error can be determined.
• L: Oceanographic platform passes over land or fixed platformmoves dramatically.
  
• M: Known instrument malfunction.
  
• O: Original units differ from those listed in the convers_variable units attribute. See quality control report for details.
  
• P: Position of platform or its movement are uncertain. Data should be used with caution.
  
• Q: Questionable - data arrived at DAC already flagged as questionable/uncertain.
• R: Replaced with an interpolated value. Often done prior to arrival at the DAC. Flag is used to note condition.
  
• S: Spike in the data. Usually one or two sequential data values (sometimes up to 4 values) that are drastically out of the current data trend. Spikes occur for many reasons including power surges, typos, data logging problems, lightning strikes, etc.
  
• T: Time duplicate
  
• Z: Data passed evaluation.

**At the request of the WOCE Data Committee, all WOCE files (version 300) contain longitude units in the (+E/-W) 180 degrees convention. An example of the WOCE ASCII file is located in Appendix 1. The RVSMDC standard longitude units are from 0-359.99 degrees East. All data that are not included in WOCE have the 0-359.99 degrees East units convention.

As an example of the usage of the flag variable, assume that a WOCE netCDF file contains only time, latitude, longitude, atmospheric pressure, and air temperature data along with a flag variable. Based on Table1, all five variables will be quality controlled and each will have a uniqueqcindex. If the values for the first record of all five variables pass all quality control checks, then the first record of the flagvariable will contain "ZZZZZ"; i.e. the flag variable contains QC flags for each QC variable, in this example 5 flags. However, if the second record contains a non-sequential time, but good latitude and longitude values, a pressure value of 1090 mb, and a temperature that is 6 standard deviations from the climatology, then the second record offlag will contain "CZZBG". The qcindex allows access to the flags for any variable. For example, the flag for the second record for atmospheric pressure (qcindex=4) is a "B" indicating the pressure value is out of bounds.

The global attributes in the WOCE DAC ASCII files include parameters that apply to all the variables in the file or to the file in general. Again a mix of data and metadata are included.

a) title

A descriptive title highlighting the platform name, location, and special instrument characteristics. Often used to title plots of the data from the ASCII file. Ex: "Bridge observations - R/V Vidal Gormaz - PR_14_/04 Cruise"

b) site

This attribute will contain either the alphanumeric R/V name or buoy location name.

c) elev

Stores the geographic elevation of the site in meters above sea level. This value is zero for ships and buoys.

d) ID

Either the ship/platform identification, call sign, or WMO number.

e) platform

Instrument system that recorded the data. For example: IMET, PAM, ATLAS, unspecified tower, bridge report, hand held instruments, etc.

f) facility

The institution or country that either collected the data or are the primary holder of the data. For example: NOAA, PMEL, WHOI, University of Washington, Chile, etc. Also included is the name of the PI or primary data provider for the original files.

g) fsu_version

The current version number or the data in the file.

h) missing_value

A missing value of -9999 that is used for all variables.

i) special_value

A special value (set equal to -8888) is used to indicate that data were present in the original file, however the data were either:

a) coded and the value listed did not fit the code range (no qcindex for data)

or

b) an overflow value that does not fit the memory space allocated by our internal format.

j) start date

The first date of the data in the file. Coded as DD MMM YYYY where
DDDay number (01 to 31)
MMMMonth (JAN,FEB,MAR,APR,MAY,JUN,JUL,AUG,SEP,OCT,NOV,DEC)
YYYYFour digit year (ex: 1992).

k) end date

The last date of the data in the file. Coded the same as start date.

l) EXPOCODE

Identifier for all WOCE cruises created by the WOCE Hydrographic Programme Office and obtained from the WOCE DIU at the University of Delaware. This identifier is appended to help match our data files to other oceanographic data sets.

m) Release_Date

Date that QC data set was released by WOCE DAC.
