Near-global, upper 2000 m estimates of preindustrial and year 2002 ocean pH, aragonite saturation state, carbon dioxide partial pressure, hydrogen ion concentration, and Revelle factor values, and their total changes caused by anthropogenic carbon accumulation in addition to the component of the changes induced by carbonate system nonlinearities (NCEI Accession 0290073)

This dataset consists of year 2002 and preindustrial (pi) OA metric values and their uncertainties (u), total OA metric changes (d) due to anthropogenic carbon accumulation to the year 2002 and the component of those changes caused by carbonate system nonlinearities (n), with associated uncertainties provided. Uncertainties were estimated using a 1000 iteration Monte Carlo simulation. Data from the upper 2000 m of the GLODAPv2.2016b mapped data product (https://doi.org/10.3334/cdiac/otg.ndp093_glodapv2), described in Lauvset et al., 2016 (https://doi.org/10.5194/essd-8-325-2016), and from the preformed properties product of Carter et al., 2021 (https://doi.org/10.1029/2020GB006623) were used to make these estimates. Calculation details are described in Fassbender et al., 2023 (https://doi.org/10.1029/2023GB007843). Year 2002 aragonite saturation state and pH values, and their uncertainties, are reproduced from the GLODAPv2.2016b mapped data product (https://doi.org/10.7289/v5kw5d97) and are provided here for user convenience with the permission of the original data producer.
