Accurate estimates of atmosphere-ocean balances and fluxes of greenhouse gases and aerosols are fundamental for Earth-System models forecasting the climate change, and for Earth Observation estimates of oceanic sinks and sources coupling satellite imagery with reverse modelling. The standard formulations are 24 and 36 years old, and recent alternatives have emerged. We developed a framework congregating the geophysical processes involved, customizable with alternative formulations, and that can be used as basis for novel couplers of atmospheric and oceanographic model components. We tested it with fine resolution data from the European coastal ocean. Although the solubility formulations agreed well, their minor divergences yielded differences of many tons of greenhouse gases dissolved at the ocean surface. The transfer velocities largely mismatched their estimates, in part consequence of the standard formulation not considering factors that were proved determinant at the coastal ocean. Climate Change research requires further calibration and validation of atmosphere-ocean interactions.
