56 | !! ** Purpose : Compute the surface boundary contition on TRI 11 |
---|
57 | !! passive tracer associated with air-mer fluxes and add it |
---|
58 | !! to the general trend of tracers equations. |
---|
59 | !! |
---|
60 | !! ** Method : - get the atmospheric partial pressure - given in pico - |
---|
61 | !! - computation of solubility ( in 1.e-12 mol/l then in 1.e-9 mol/m3) |
---|
62 | !! - computation of transfert speed ( given in cm/hour ----> cm/s ) |
---|
63 | !! - the input function is given by : |
---|
64 | !! speed * ( concentration at equilibrium - concentration at surface ) |
---|
65 | !! - the input function is in pico-mol/m3/s and the |
---|
66 | !! TRI concentration in pico-mol/m3 |
---|
67 | !! |
---|
68 | !! *** For Idealized Tracers |
---|
69 | !! - no need for any temporal references, |
---|
70 | !! nor any atmospheric concentration, nor air -sea fluxes |
---|
71 | !! - Here we fixe surface concentration to 1.0 Tracer-Unit/m3 |
---|
72 | !! - Then we add a decay (radioactive-like) to this tracer concentration |
---|
73 | !! - the Half life deccay is chosen by the user, depending of the experiment. |
