Quantification of the air-sea CO2 flux is possible using measurements of the oceanic and atmospheric partial pressures of CO2 (pCO2) in conjunction with a parameterization of the gas transfer across the sea-air interface.
As the observations from SOCONET can only cover a tiny fraction of the spatio-temporal pCO2 field of the global surface ocean, interpolation and mapping methods are being extensively used to estimate values in all the periods and areas not directly observed, to obtain continuous air-sea CO2 flux fields over larger areas or the entire ocean.
In collaboration with the Surface Ocean pCO2 Mapping v2 (SOCOMv2) community we plan to populate this page with access to the latest CO2 flux products based on SOCONET observations, quality controlled and presented in a uniform format as the Surface Ocean CO2 Atlas.
