This data file contains the underway measurements ofµatmospheric xCO2 made during R/V Meteor Cruise 36/1 in the North Atlantic Ocean. The data are presented in ASCII format and can be read by using the following FORTRAN 77 code [contained in xco2air.for (File 3)]:
CHARACTER date*10, time*8, lab*1
REAL latdcm, longdcm, xco2
read (1, 10, end=999) date, time, latdcm, londcm, xco2, lab
10 format (2X, A10, 4X, A8, 4X, F6.3, 4X, F7.3, 4X, F6.2,
1 3X, A1)
Stated in tabular form, the contents include the following:
-----------------------------------------------
Variable Variable Variable Starting Ending

date Character 10 3 12
time Character 8 17 24
latdcm Numeric 6 29 34
londcm Numeric 7 39 45
xco2 Numeric 6 50 55
lab Character 1 59 59
-----------------------------------------------
The variables are defined as follows:
date is the sampling date (day/month/year);
time is the sampling 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);
xco2 is the mole fraction ofµatmospheric CO2 (ppmv) measured in
dry air;
lab is the laboratory identifier.
