*w.txt (Files 4-12)
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

| 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 theµatmospheric pressure (hPA); |
| fco2a | - | is the underway fugacity of CO2 in surface seawater (µatm) measured by the laboratory A; |
