coef_talk.dat (File 7)

This file provides the coefficients a, b, and c used to calculate TALK from the potential temperature (T) and salinity (S). Each line of the file contains a longitude, latitude, offset coefficient a (between depths MLD and 1000 m), offset coefficient a (below 1000 m), T coefficient b (between depths MLD and 1000 m), T coefficient b (below 1000 m), S coefficient c (between depths MLD and 1000 m), and S coefficient c (below 1000 m). The file is sorted by longitude and latitude and can be read by using the following FORTRAN 77 code [contained in coef_talk.for (File 2)]:

The variables are defined as follows:

lon - is the longitude for which coefficients were calculated;

lat - is the latitude for which coefficients were calculated;

coef1 - is the offset coefficient a (for depths between MLD and 1000 m);

coef2 - is the offset coefficient a (for depths below 1000 m);

coef3 - is the T coefficient b (for depths between MLD and 1000 m);

coef4 - is the T coefficient b (for depths below 1000 m);

coef5 - is the S coefficient c (for depths between MLD and 1000 m); and

coef6 - is the S coefficient c (for depths below 1000 m).
