The calculated emissions fluxes, salinity and seawater concentrations can be saved in output in variables:
$CASEROOT/user_nl_cam | |
|---|---|
6 | fincl2 = 'OCN_FLUX_DMS', 'OCN_FLUX_CH3CHO', 'OCN_FLUX_CH3COCH3', ! emissions fluxes |
NOTE: The ocean emissions are NOT included in the SF{species} output variables.

UNDER THE HOOD
In this framework, the air-sea exchange of a given soluble gas is determined by (i) solubility; (ii) kinetics; and (iii) concentration gradient at the interface. The solubility (effective Henry's law constant) is given in the FORTRAN source code, and the kinetics (e.g., the transfer velocities) will be calculated based on local physical forcing in the ocean and the atmosphere. The concentration in the atmosphere is explicitly solved in the atmospheric model, the local surface seawater concentration, ideally, should be explicitly solved in the ocean model. Unfortunately, for most of the trace gases of interest, the ocean biogeochemical processes affecting the sources and sinks in the seawater remain unclear. Therefore user needs to provide the input surface seawater concentration fields.
