Hi Carlos,

I used the T and S diagnostics (in ROMS Agrif, but there shouldn't be a difference with Rutgers ROMS) for this recent paper: Barrier layers in the tropical South Atlantic: mean dynamics and submesoscale effects, 2014, JPO 44, 265-288.

ps: are you Carlos Lentini, by any chance?

Hi,
when you run with MPI, you need to send the job through mpirun:
mpirun -np n ./roms roms.in
where n=number of total processors used = 8 in your case.

See page 29 of the latest documentation file.

best,
Milena

I found that 1<theta_s<20 and 0<theta_b<1 Yes, but that is a huge range of values. For example, I first chose thetas=6, thetab=0, hc=20 (I wanted more levels in the surface mixed layer), and the grid was VERY unstable (even reducing the time step several times wouldn't help). Just by going to ...

Hi there! One thing I can tell you for sure is don't mess too much with theta_s, theta_b and hc, as the grid you get can become very unstable. Once you found a set of parameters that works for you, keep it! I had luck with theta_s=5, theta_b=0 or 0.4 (for a South Atlantic and Eastern Pacific ...

Hi schen, I just did exactly the same thing (not with TS_MPDATA, but it shouldn't make a difference). You don't mention in your post if you modified other routines or not, but there are another few places where you need to tell ROMS that DiaTwrk has two additional diagnostic tracers: 1) in mod_param ...

You need to define OPT_PERTURBATION in cppdefs (and FORWARD_MIXING if you want to read vertical mixing coefficients from the forward model history files). As input files you really need only the forward model trajectory (FWDNAME=ocean_his.nc), but ROMS requires the following files anyway: the ...
