a10pco2.for (File 4)

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)]:

           REAL jday, latdcm, londcm, sst, salt, airpre, airxco2
           REAL airpco2, waterpco2

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 µatm);
waterpco2  -  is the sea surface water pCO2 (in µatm).
