Data are grouped by decade, with each file being about 800 MB. Not all files contain the same number of years (e.g., 1982-1989). The size for each variable (1982-2022) is between 2.5 and 3.5 GB. Product description This dataset contains a global gridded dataset of sea-air carbon dioxide fluxes ( F C O 2 ) for subseasonal to decadal studies. The product is available from 1982 through 2022 and is at an 8-daily by 0.25° by 0.25° resolution. FCO2 is calculated using the bulk formulation of flux: ( f C O 2 s e a − f C O 2 a ...
