6   -! !ROUTINE: The nitrate equation \label{sec:nitrate}
7   -!
8   -! !INTERFACE:
9   - subroutine ammonium(nlev,dt,cnpar,nus,gams,cc)
10   -!
11   -! !DESCRIPTION:
12   -! This subroutine computes the balance of ammonium in the form
13   -! \begin{equation}
14   -! \label{SEq}
15   -! \dot{S}
16   -! = {\cal D}_S
17   -! - \frac{1}{\tau^S_R}(S-S_{obs})
18   -! \comma
19   -! \end{equation}
20   -! where $\dot{S}$ denotes the material derivative of the nitrate $N$, and
21   -! ${\cal D}_N$ is the sum of the turbulent and viscous transport
22   -! terms modelled according to
23   -! \begin{equation}
24   -! \label{DN}
25   -! {\cal D}_N
26   -! = \frstder{z}
27   -! \left(
28   -! \left( \nu^N_t + \nu^N \right) \partder{N}{z} - \tilde{\Gamma}_N
29   -! \right)
30   -! \point
31   -! \end{equation}
32   -! In this equation, $\nu^N_t$ and $\nu^N$ are the turbulent and
33   -! molecular diffusivities of nitrate, respectively,
34   -! and $\tilde{\Gamma}_N$
35   -! denotes the non-local flux of nitrate, see
36   -! \sect{sec:turbulenceIntro}. In the current version of GOTM,
37   -! we set $\nu^N_t = \nu^\N$ for simplicity.
38   -!
39   -! Horizontal advection is optionally
40   -! included (see {\tt obs.nml}) by means of prescribed
41   -! horizontal gradients $\partial_xN$ and $\partial_yN$ and
42   -! calculated horizontal mean velocities $U$ and $V$.
43   -! Relaxation with the time scale $\tau^N_R$
44   -! towards a precribed (changing in time)
45   -! profile $N_{obs}$ is possible.
46   -
47   -! Inner sources or sinks are not considered.
48   -! The surface freshwater flux is given by means of the precipitation
49   -! - evaporation data read in as $P-E$ through the {\tt airsea.nml} namelist:
50   -! \begin{equation}
51   -! \label{S_sbc}
52   -! {\cal D}_S = S (P-E),
53   -! \qquad \mbox{at } z=\zeta,
54   -! \end{equation}
55   -! with $P-E$ given as a velocity (note that ${\cal D}_S$ is the flux in the
56   -! direction of $z$, and thus positive for a \emph{loss} of nitrate) .
57   -! Diffusion is numerically treated implicitly,
58   -! see equations (\ref{sigmafirst})-(\ref{sigmalast}).
59   -! The tri-diagonal matrix is solved then by a simplified Gauss elimination.
60   -! Vertical advection is included, and it must be non-conservative,
61   -! which is ensured by setting the local variable {\tt adv\_mode=0},
62   -! see section \ref{sec:advectionMean} on page \pageref{sec:advectionMean}.
