Coupling GOTM and MITgcm

[Georges Djoumna]

Hello all,

I am a new user of GOTM. I am using GOTM as a turbulent library in the MITgcm model. I've written routines to compute the 

square of the buoyancy frequency  NN and the shear frequency SS, I also have a routine to convert all 3D-vectors to 1D-vectors and the reverse.  My question is about how to run the model? Where should I put  gotmrun.nml? When I copy  the subdirectory kepsilon_nml/ to the directory with the MITgcm executable, I have the following error 

        --------------------------------------------------------

         

    init_tridiagonal

    init_gotm

 ------------------------------------------------------------------------

        reading model setup namelists..

 FATAL ERROR: I could not read the "model_setup" namelist

init_gotm

Any suggestion is welcome

Thanks a lot.

you should regard GOTM as a library and only link in the turbulence
library (and the util library) when you compile MITgcm.

When you want to run the program you need a gotmturb.nml namelist file
that will take care of initialising the turbulence module.

This link shows how the interface between our 3D model - GETM - and GOTM
is made. It might serve as inspiration.

Hopefully the link works:

I know of 3D models that have implemented support for using
GOTM as turbulence module. I don't have access to these interface
routines as those who have coded them have not found it necessary to
provide the code. It might be that you - on a bilateral level - can get
further code for inspiration.

Hi,

MOM4p1 has interfaced to GOTM. You may find some inspiration there as
well. See

http://data1.gfdl.noaa.gov/~arl/pubrel/r/mom4p1/src/mom4p1/doc/mom4_manual.html

for information regarding how to access the code.

I would be interested to hear about your progress with the coupling of the
GOTM turbulence module to MITgcm. Does it work ? What is your experience ?

Do other colleagues have experience with coupling these two models ?

Kind regards,

Hans.

Dear Hans,

I've restarted  working on the coupling of the GOTM turbulence module to MITgcm last week. 

I have to validate the coupling using classical turbulence problem such as  the wind mixed layer deepening experiment.

I will let you know how it works by the end August. I think that the coupling should work, because other colleagues have experience with the coupling of these two models: 

L.I. Enstad at al (2008) have coupled GOTM and MITgcm to study the   Dissolution of  CO2 in a  lake,

 "Dissolution of a CO2 lake, modeled by using an advanced vertical turbulence mixing scheme"

L. Jackson et al.(JPO2008): " A Parameterization of Shear-Driven Turbulence for Ocean Climate Models".

Dear all,

I am new to GETM, I am planning to do  3D lake simulations with hourly wind, incoming solar radiation, long-wave radiation, air temperature, cloud cover as the forcing.  Can anyone guide me about where to start?  Thanks a lot

Hello

Three things

1) You are on the wrong mailing list

2) Please don't hijack an existing mail-thread by just changing the
subject line.

3) getm.eu will provide you plenty of information on how to download and
compilethe code, run test-cases etc. When you have done that you'll
have a much better feeling for setting up your own simulation.
