The files in this site contain the monthly pCO2 data in 0.25 degree box areas from 2002 to 2008 and the distribution maps.

These were originally published in:Nakaoka, et al. (2013), Biogeosciences, 10, 6093-6106.

The data is provided as .csv files.

Please note that the related data of sea surface temperature, mixed layer depth, chlorophyll-a concentration and sea surface salinity are not included in the files.
