Ocean CFC reconstructed data product

A global CFC Data product is derived used the Time-Corrected Method (TCM) in order to estimate CFCs and SF6 ocean concentration back to 1940. The Green's functions (GFs), describing the steady-state transport from the surface to the ocean interior, is solved, constrained by observations. From the GFs, we reconstruct global tracer concentrations (and associated uncertainties) in the ocean interior at annual resolution (1940–2021). The spatial resolution includes 50 neutral density levels that span the water column along World Ocean Circulation Experiment/Global Ocean Ship-Based Hydrographic Investigations Program lines.
