The OceanFlux Greenhouse Gases project have developed a climatology of carbon dioxide normalised to the year 2010 (Goddijn-Murphy et al. 2015). This has been developed using a re-analysed version of the international SOCAT dataset. Using this as a basis the project team have been generated an estimate of the atmosphere-ocean carbon dioxide fluxes for 2010 and these data are available below as NetCDF data.
