tco2_*.dat (Files 15-19)

These files provide the interpolated TCO₂ fields calculated annually and for each quarter (tco2_ann.dat, tco2_djf.dat, tco2_mam.dat, tco2_jja.dat, and tco2_son.dat). The files are sorted by longitude and latitude and can be read by using the following FORTRAN 77 code [contained in tco2dat.for (File 6)]:

            
            REAL lon, lat, dep, mld, trco2, tmp, aou, sal
     
            read (1, 10, end=999) lon, lat, dep, mld, trco2, tmp, 
         1 aou, sal
          
    10    format (F7.1, 1X, F6.1, 1X, F7.1, 1X, F7.1, 1X, F9.1,
         1 1X, F7.3, 1X, F7.3, 1X, F7.3)
         
 

Variable	Variable type	Variable width	Starting column	Ending column
lon	Numeric	7	1	7
lat	Numeric	6	9	14
dep	Numeric	7	16	22
mld	Numeric	7	24	30
tco2	Numeric	9	32	40

sal	Numeric	7	58	64

The variables are defined as follows:

lon - is the longitude for which TCO₂ was calculated;

lat - is the latitude for which TCO₂ was calculated;

dep - is the depth for which TCO₂ was calculated (m);

mld - is the maximum layer depth (m);

talk - is the total carbon dioxide (µmol/kg);

tmp - is the temperature (°C);

aou - is the apparent oxygen utilization (µmol/kg); and

sal - is the salinity.
