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)]:

Variable	Variable type	Variable width	Starting column	Ending column
lon	Numeric	6	1	6
lat	Numeric	6	8	13

coefb	Numeric	11	28	38

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).
