coef_tco2.dat (File 8)
This file provides the coefficients a, b, c, and d used to calculate TCO2 from the T, apparent oxygen utilization (AOU), and S. Each line of the file contains a longitude, latitude, offset coefficient a (below MLD), T coefficient b (below MLD), AOU coefficient c (below 1000 m), and S coefficient d (below MLD). The file is sorted by longitude and latitude and can be read by using the following FORTRAN 77 code [contained in coef_tco2.for (File 3)]:
REAL lon, lat, coefa, coefb, coefc, coefd read (1, 10, end=999) lon, lat, coefa, coefb, coefc, coefd 10 format (F6.1, 1X, F6.1, 2X, F11.4, 1X, F11.5, 1X, F12.6, 1 1X, F11.5)
Stated in tabular form, the contents include the following:
| Variable | Variable type | Variable width | Starting column | Ending column |
|---|---|---|---|---|
| lon | Numeric | 6 | 1 | 6 |
| lat | Numeric | 6 | 8 | 13 |
| coefa | Numeric | 11 | 16 | 26 |
| coefb | Numeric | 11 | 28 | 38 |
| coefc | Numeric | 12 | 40 | 51 |
| coefd | Numeric | 11 | 53 | 63 |
The variables are defined as follows:
| lon | - | is the longitude for which coefficients were calculated; |
| lat | - | is the latitude for which coefficients were calculated; |
| coefa | - | is the offset coefficient a (for depths below MLD); |
| coefb | - | is the T coefficient b (for depths below MLD); |
| coefc | - | is the AOU coefficient c (for depths below MLD; and |
| coefd | - | is the S coefficient d (for depths below MLD). |
