Duke et al. (2023): Estimating marine carbon uptake in the northeast Pacific using a neural network approach

Patrick J. Duke, Roberta C. Hamme, Debby Ianson, Peter Landschützer, Mohamed M. M. Ahmed, Neil C. Swart, Paul A. Covert IN: Biogeosciences, https://doi.org/10.5194/bg-20-3919-2023

Here the authors use a neural network approach to interpolate sparse observations, creating a monthly gridded seawater partial pressure of CO₂ (pCO₂) data product from January 1998 to December 2019, at 1/12^∘ ×1/12 ^∘ spatial resolution, in the northeast Pacific open ocean, a net sink region. The data product (ANN-NEP; NCEI Accession 0277836) was created from pCO₂ observations within the 2021 version of the Surface Ocean CO₂ Atlas (SOCAT) and a range of predictor variables acting as proxies for processes affecting pCO₂ to create nonlinear relationships to interpolate observations at a spatial resolution 4 times greater than leading global products and with better overall performance.
