[MITgcm-support] balancing the heat equation

[Martin Losch]

Hi Nicolas/Allison,

the safest way to find out what diagnostics are available is to have  
a look in the respective "diagnostics_init" files. The are usually:
pkg/diagnostics/diagsnostics_init_main.F (for general stuff, e.g.  
TOTTTEND)
pkg/$pkg/$pkg_diagnostics_init.F
so for all the advective and diffusive stuff you'd have to look in  
pkg/generic_advdiff/gad_diagnostics_init.F (which is already a  
counter example to the about scheme, oh well).

Anyway, for checking the balance offline you'll find everything in  
these two files except for the non-local transport of KPP. Since you  
have all the other terms, you could assume that the residual is the  
non-local transport of KPP. If you don't trust the MITgcm (shame on  
you (-:) then you'll have to do the modifications suggested earlier  
in this thread.
