This file provides underway measurements of pCO2 during R/V Meteor Cruise 22/5. Each line of the file contains a sampling date (month/date/year), latitude, longitude, underway measurements of sea surface temperature, salinity, air pCO2, and water pCO2. The file is sorted by longitude and can be read by using the following FORTRAN 77 code [contained in a10pco2.for (File 4)]:
Stated in tabular form, the contents include the following:REAL jday, latdcm, londcm, sst, salt, airpre, airxco2 REAL airpco2, waterpco2 CHARACTER sect*3, date*10, time*5 read (1, 10, end=999) sect, date, time, jul, latdcm, londcm, 1 sst, salt, pre, xco2, pco2a, pco2w 10 format (3X, A3, 3X, A10, 3X, A5, 2X, F9.3, 1X, F7.2, 1X, 1 F7.2, 1X, F7.2, 1X, F7.2, 1X, F7.1, 2X, F7.2, 3X, F7.1, 2 3X, F7.1)

The variables are defined as follows:
sect - is the WOCE Section number;
date - is the sampling date (day/month/year);
time - is the sampling time (GMT);
jday - is the julian day of the century relative to 1900 with time of the day represented as a fractional day (i.e., noon on 1/1/1900 = 0.5);
latdcm - is the latitude of the sampling (in decimal degrees; negative values indicate the Southern Hemisphere);
londcm - is the longitude of the sampling (in decimal degrees; negative values indicate the Western Hemisphere);
sst - is the sea surface temperature (in °C);
salt - is the sea surface salinity (on the PSS);
airpre - is the atmospheric pressure (in atm);
airxco2 - is the observed mole fraction of pCO2 in air [in ppm (dry air)];
airpco2 - is the air pCO2 (in ľatm);
waterpco2 - is the sea surface water pCO2 (in ľatm).
