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)
Stated in tabular form, the contents include the following:
| 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 |
| tmp | Numeric | 7 | 42 | 48 |
| aou | Numeric | 7 | 50 | 56 |
| 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. |
