4. Output type and frequency

The Biotic simulation represents only one equilibrium run per model. Therefore only time-averaged fields of the seasonal cycle of the final "steady-state" solution need be saved. Modelers must submit results based on an average of the last 10 years of the simulation. Below are listed the required fields. The spatial dimension is indicated in square brackets; another dimension must be added for time, i.e., 12 months per year):

1. [3-D] Monthly mean tracer concentrations for both active tracers: potential temperature T (degrees C) and salinity S (psu);
2. [3-D] Monthly mean tracer concentrations for all five passive tracers ( [PO4], [DOP], [O2], [DIC], and [Alk]) for the whole water column (mol/m^3);
3. [2-D] Monthly mean pCO2surf = CO2surf/alphaC (uatm);
4. [2-D] Monthly mean dpCO2 = (CO2surf - CO2sat*P/Po) (uatm);
5. [2-D] Monthly mean air-sea CO2 flux FgDIC (mol/m^2/s);
6. [2-D] Monthly mean air-sea O2 flux FgO2 (mol/m^2/s);
7. [2-D] Monthly mean virtual DIC flux FvDIC (mol/m^2/s);
8. [2-D] Monthly mean virtual flux of total Alkalinity FvAlk (eq/m^2/s);
9. [2-D] Monthly mean downward flux of particulate organic phosphorus interpolated to the compensation depth (75 m) PnewPOP (mol/m^2/s);
10. [2-D] Monthly mean total downward flux of dissolved organic phosphorus (DOP) interpolated to the compensation depth (75 m) PnewDOP (mol/m^2/s);
11. [2-D] Monthly mean advective net downward flux of DOP interpolated to the compensation depth (75 m) PnewDOPa (mol/m^2/s);
12. [2-D] Monthly mean diffusive net downward flux of DOP interpolated to the compensation depth (75 m) PnewDOPd (mol/m^2/s); and
13. [2-D] Monthly mean convective net downward flux of DOP interpolated to the compensation depth (75 m) PnewDOPc (mol/m^2/s).
