Hi dear,

1. I want to know equation of fennel model in ROMS, where is BIO advection term

BIO equation according to fennel et al. 2006
(I express partial derivative is 'P' and total derivative is 'D' in this topic.)

for instance,
PChl/Pt = rho*mu*Chl - g*Zoo*Chl/Phy - ... - tau*(SDet+Phy)*Chl = sink and source term : time rate of change

therefore,
DChl/Dt = (1)PChl/Pt + (2)u*PChl/Px + (2)v*PChl/Py + (2)w*PChl/Pz
(1)time rate of change (2)advection
is right?

if so,
2. I want to know how compute chlorophyll value in output file of his, avg

Chlorophyll value in output file is calculated by only time rate of change?
or
chlorophyll value in output file is calculated include advection?

I need to help you.

All the Fennel tracers are advected in pre_step3d.F and step3d_t.F when T and S are advected. Same with diffusion. The loops go over 1,NT(ng) where NT is the total number of tracers, including passive tracers and the bio tracers.
