uwpco2.dat (File 7)

This file contains underway pCO₂ measurements taken along the cruise track during the R/V Meteor Cruise 18/1. Each line of the file contains a sampling date; sampling time; latitude; longitude; and measurements of sea surface salinity, temperature, and pCO₂. The file is sorted by date and time and can be read by using the following FORTRAN 77 code [contained in uwpco2dat.for (File 4)]:

where

day - is the sampling day;

month - is the sampling month;

year - is the sampling year;

time - is the sampling time (GMT);

latdcm - is the latitude of the station (in decimal degrees; negative values indicate the Southern Hemisphere);

londcm - is the longitude of the station (in decimal degrees; negative values indicate the Western Hemisphere);

salt - is the sea surface salinity;

temp - is the sea surface temperature (^oC);

pco2 - is the sea surface pCO₂ (µ atm).
