Provenance : Omon ((isd.003))

Processing Notes : Concentrations of all 3D tracers in the uppermost ocean layer. See first table in Oyr for a complete list of these tracers. "Tracer" concentations should be reported even if they are diagnosed rather than prognostically calculated.

Description : Surface mole concentration (number of moles per unit volume: molarity) of the natural-analogue carbonate anion (CO3). A natural analogue is used to simulate the effect on a modelled variable of imposing preindustrial atmospheric carbon dioxide concentrations, even when the model as a whole may be subjected to varying forcings.
