Ocean Modeling Discussion

Dear all,

I am having troubles trying to understand why my nitrate_vertical_advection field (NO3_vadv) is different from my nitrate_multiplied_by_vertical_velocity field (w*NO3, w is true vertical velocity - not Omega), to within a constant.
I mean I should have similar trend, right? However, I do ...

Hi everybody,

I'm working with NEMURO model.
Comparing ligth inhibition equation written in the Rutgers code vs ligth inhibition in Kishi 2007 paper, I have noticed that there is two different formulations: Platt 1980 for Rutger and Steele 1962 for Kishi.

So could you explain why do you code ...

Hey

Thank you Kate. I have tried it and my nitrogen budget is constant.
So I guess I use the right way.

Cheers,

The two versions of ROMS have different timestepping schemes. It's just part of the tracer timestep.

Actually, I try to work with NEMURO coupled to ROMS Agrif,

So If I change
(1) the loading of tracers arrays to
Bio(i,k,ibio)= max ( t(i,j,k,nnew,itrc), 0.0)
and
(2)the extracting of Bio to ...

Hello,

I working on NEMURO model. In the last loop of the code, in the "Update global tracer variables" part, we have:

DO itrc=1,NBT
ibio=idbio(itrc)
DO k=1,N
DO i=Istr,Iend
t(i,j,k,nnew,ibio)=MAX(t(i,j,k,nnew,ibio)+(Bio(i,k,ibio)-Bio_bak(i,k,ibio))* Hz(i,j,k), 0.d0)
END DO
END DO
END DO ...
