These 9 data files contain the underway measurements of surface seawater fCO2 and hydrographic parameters made by participants in the systems intercomparison exercise during the R/V Meteor Cruise 36/1 in the North Atlantic Ocean. All files have the same ASCII format and can be read by using the following FORTRAN 77 code [contained in fco2wat.for (File 2)]:
CHARACTER date*10, time*8
INTEGER course
REAL latdcm, londcm, speed, temp, salt, press, fco2a, fco2b
REAL fco2c, fco2d, fco2e, fco2f, fco2g, fco2h

The variables are defined as follows:
date is the sampling date (day/month/year);
time is the sampling time [Greenwich mean time (GMT)];
latdcm is the latitude of the sampling location (decimal
degrees; negative values indicate the Southern Hemisphere);
londcm is the longitude of the sampling location (decimal
degrees; negative values indicate the Western Hemisphere);
speed is the speed of the ship during the measurements (kn);
course is the course of the ship during the measurements
(degrees);
temp is the sea-surface temperature (C);
salt is the sea-surface salinity [on the Practical Salinity Scale
(PSS)];
press is theľatmospheric pressure (hPA);
fco2a is the underway fugacity of CO2 in surface seawater
(ľatm) measured by the laboratory A;
fco2b is the underway fugacity of CO2 in surface seawater
(ľatm) measured by the laboratory B;
fco2c is the underway fugacity of CO2 in surface seawater
(ľatm) measured by the laboratory C;
fco2d is the underway fugacity of CO2 in surface seawater
(ľatm) measured by the laboratory D;
