9 | CCC PURPOSE : |
10 | CCC --------- |
11 | CCC compute the now trend due to biogeochemical processes |
12 | CCC and add it to the general trend of passive tracers equations. |
13 | CCC |
14 | CCC Three options: |
15 | CCC Default option : no biological trend |
16 | CCC If 'key_trc_npzd' : NPZD model |
17 | CCC IF 'key_trc_lobster1' : LOBSTER1 model |
18 | CCC |
19 | CC METHOD : |
20 | CC ------- |
21 | CC each now biological flux is calculated in FUNCTION of now |
22 | CC concentrations of tracers. |
23 | CC depending on the tracer, these fluxes are sources or sinks. |
24 | CC the total of the sources and sinks for each tracer |
25 | CC is added to the general trend. |
26 | CC |
27 | CC tra = tra + zf...tra - zftra... |
28 | CC | | |
29 | CC | | |
30 | CC source sink |
31 | CC |
32 | CC |
33 | CC IF 'key_trc_diabio' key is activated, the biogeochemical |
34 | CC trends for passive tracers are saved for futher diagnostics. |
35 | CC |
36 | CC multitasked on vertical slab (jj-loop) |
37 | CC |
38 | CCC MODIFICATIONS: |
39 | CC -------------- |
40 | CC original : 95-02 (M. Levy, NPZD model) |
41 | CC 99-07 (M. Levy, LOBSTER1 model) |
