Ocean Modeling Discussion

Hi Kate,
Thanks for reply. I do not understand your method. Does that mean I should remove rmask_io from the computation for the diagnostics in Fennel model, or using rmask instead of rmask_io?

Recently, I am running the Bio_Fennel model and ready to simulate the pCO2 in seawater distribution in China seas. I read the subroutine for the calculating the pCO2 in Fennel model, and find there is one choice about defining WET_DRY CPP, such as follows: DiaBio2d(i,j,ipCO2)=pCO2(i) # ifdef WET_DRY ...

Recently, I am trying to output a new diagnostics_bio variable, which is the pCO2 in the vertical of seawater using Bio_Fennel Model. And the output routine in bio_Fennel.h was added as follow: #ifdef CARBON !---------------------------------------------------------------------- ! CALCULATING ! pCO2 ...

Recently, I am using the QCCORECTION method, and I find the function in set_vbc.F as follows: stflx(i,j,itemp)=stflx(i,j,itemp)+ dqdt(i,j)*(t(i,j,N(ng),nrhs,itemp)-sst(i,j)) I have made the dqdsst and SST in the forcing file. The upper function is using the dqdt and sst to influence the surface heat ...

Thank you Alazhar
I have defined SOLAR_SOURCE. Meanwhile I checked my solar shortwave radiation flux (swrad) forcing, and there is nothing wrong. Now, the results of the model are being normally after changing my initial conditions. Thanks for your aopinions.

Thank you spitz
I still set the initial concentrations of the tracers except the NO3 1e-6 yesterday, and it performed normally with the TS_MPDATA. So I don't think the small value is the reason for the problem I met with. But I will pay attention to what you have mentioned. Thank you very much.

Thank you John
I changed my initial conditions for the tracers except the NO3 and ran the model with the TS_MPDATA difference method. It performed normally at last. So maybe it's the initial conditions that resulted in the problem which I mentioned before.

Thank you John I did not change any of parameter setting in the bio_fennel.in, and I defined every boudary as a wall. I did not set any biologically related cpp options but just defined the bio_fennel. The plots I posted are the average of the month 3 of the ROMS running with the different ...

Thank you kfennel
Yes,the initial concentrations for my biological variables are positive.I used the WOA2009 for the NO3 initial concentration, and set the initial concentrations of the other tracers le-6, such as phytoplankton, zooplankton,NH4,Chlorophyll,LdeN,SdeN.

Dear everyone : recently I am runing ROMS coupled with Fennel bio model , But the result show many problems. I chosed TS_MPDATA difference, but only NO3 proferm good, other variables didn't grow and all are negative and cannot change with time. U know, TS_MPDATA should result in positive numbers. I ...
