  abstract:
    en: 'This dataset contains spatial distribution of surface ocean pH (total hydrogen
      scale), acidity (or hydrogen ion activity, unit: nmol/kg, or 10^-9 mol/kg) and
      Revelle Factor (a measure of the ocean''s buffer capacity, unitless) on a 1x1
      degree global grid (Longitude: [20.5:1:379.5], Latitude: [-89.5:1:89.5]) in
      all 12 months of the years from 1770 to 2100 (1770, 1780, 1790, ..., 2100).
      This data product is produced by combining a recent observational seawater carbon
      dioxide (CO2) data product, i.e., the 6th version of the Surface Ocean CO2 Atlas
      (1991-2018, ~23 million observations), with temporal trends at individual locations
      of the global ocean from a robust Earth System Model (ESM2M), to provide a high-resolution
      regionally varying view of global surface ocean pH, acidity, and the Revelle
      Factor. The climatology extends from the pre-Industrial era (1770 C.E.) to the
      end of this century under historical atmospheric CO2 concentrations (pre-2005)
      and the Representative Concentrations Pathways (RCP2.6, RCP4.5, RCP6.0 and RCP8.5,
      post-2005) of the Intergovernmental Panel on Climate Change (IPCC)’s 5th Assessment
      Report (AR5). By linking the modeled pH trends to the observed modern pH distribution,
      the climatology benefits from recent improvements in both model design and observational
      data coverage, and is likely to provide improved regional OA trajectories than
      the model output could alone, therefore, will help guide the regional OA adaptation
      strategies. Revelle Factor is defined as the ratio between the fractional change
      in pCO2 to the fractional change in dissolved inorganic carbon (DIC). This dataset
      is available in netCDF format. Some plots and animation files are also available
      for your presentation purposes. For details of the calculation and gridding
      method, please refer to Jiang, L.-Q., B. R. Carter, R. A. Feely, S. Lauvset,
      and A. Olsen (2019), Surface ocean pH and buffer capacity: past, present and
