The data in JTECH-D-13-00137.nc includes the model inputs and outputs published in "A global surface ocean fCO2 climatology based on a feed-forward neural network". DOI:10.1175/JTECH-D-13-00137.1 A new method based on DOI:10.1175/JTECH-D-13-00137.1 was developed to model surface ocean CO2. The data include the inputs and outputs of the model. The details of the method is being documented for publication.
