2002-2019 Global Ocean pH Grid Data Products

Dataset Overview

Global ocean pH data product based on step forward feedback neural network algorithm Based on the K-fold cross validation method and the continuous observation data of several marine fixed-point observation stations,the validation of pH data was completed. The average interpolation error of the global ocean pH is less than 0.02,and the average error between the model and the observation data of each fixed point station is 0.007-0.012,indicating that the model can reproduce the change rule of the global ocean pH in the past 30 years.
