Hi everyoneI noticed that when the package (MNC) is active in themodel, I can not introduce more than one tracer to my model and the error is as follows:
PTRACERS_MNC_INIT ERROR: PTRACERS_names( 2) is blank--please name it in 'data.ptracers'
How can I havemore tracers with this package?
Thanks if you guide me

Hi,
I am running some simulations with the KPP package enabled, but I think I have a strange problem reading parameters from data.kpp. I noticed this because I changed some parameters (difm0, difs0 and dift0) without having any effect on my simulation.
The output stream from my simulation suggests that data.kpp is being read (i.e. I get the lines "KPP_INIT: opening data.kpp ? OPEN_COPY_DATA_FILE: opening file data.kpp ... KPP_INIT: finished reading data.kpp?).
However if I try to trip the simulation up by inserting things which don?t make sense into data.kpp, for example setting "difm0 = Donald?, the simulation carries on as usual with the default value for difm0 and no error messages. In contrast, if I insert something silly into data.icefront (e.g. icefrontthetasurface = Donald), the simulation immediately stops. This suggests to me that somehow difm0 (and perhaps the other parameters in data.kpp) are not actually being read.
This reminds me a little of another message on the support list (http://mailman.mitgcm.org/pipermail/mitgcm-support/2005-July/003245.html). I?ve looked at kpp_readparms and compared it to similar files for other packages but can?t see anything amiss.
Has anyone experienced this or can offer any pointers as to what might be going on?
Many thanks,
Donald

Did you specify "useKPP=.TRUE." in data.pkg?

Hi,
Yes I did. Sorry I should have specified that. I also know that KPP is running because I?ve got the diagnostic KPPviscA printing out and it gives me variable vertical viscosity as expected for KPP under the default parameters.

Just to clarify, as in retrospect my previous email was a little confusing.
I do have "useKPP=.TRUE." in data.pkg. And I know KPP is running because I get the expected variable vertical viscosity when I print out the relevant diagnostic.
But I still have the issue with the simulation appearing to ignore the parameters in data.kpp
Thanks,
Donald

Content-Type: text/plain; charset="utf-8"
Hi every oneI want to add two tracers to my model. I set in the PTRACERS_SIZE.hthe number of tracers and set the data.ptracers file for tracers. When thenumber of my tracers is 1, I have no problem in running the model, but with theaddition of the number of tracers, the model gives an error: (PTRACERS_MNC_INIT ERROR: PTRACERS_names(? 2) is blank--please name it in 'data.ptracers')? While tracer name 2 is not blank. Do I need othersettings?Best ragard?Raheleh

Subject: [MITgcm-support] Input of warm water in depth
Message-ID: <710EFCB9-41E3-44B0-AA3C-D30624FF888A at gmail.com>
Content-Type: text/plain; charset=us-ascii
Dear all,
I am using the MITgcm with specified heat and water fluxes and relaxation for the region of the Gulf of Elat.
I would like to check how an input of warmer water entering in different depths from the boundary can effect the surrounding water.
I have tried using the obcs pkg, but specifying the temperature in the boundary seems to have a higher effect then should be, and it is not correlated with the discharge (or velocities) entering though the boundary (even when specifying velocities of zero, I still see a great effect due to the temperature of the boundary).
As far as I can tell, since I need to check the effect of the water entering in differing depths (and not only on the surface), I can not use the surface forcing via evaporation minus precipitation (EmPmRFile) or the external forcing package (runoffFile).
Any ideas?
Thanks,
Hadar Berman.
