In view of the urgent need for high coverage and high-resolution atmospheric CO 2 data in the study of carbon neutralization and global CO 2 change research, this study combines the Kriging interpolation and the Triple Collision (TC) algorithm to fuse three XCO 2 datasets, OCO-2, GOSAT, and CarbonTracker, to obtain a 1° × 1° half-monthly average XCO 2 dataset. Through a sub division of the Kriging interpolation, the average coverages of the OCO-2 and GOSAT XCO 2 interpolating datasets are increased by 53.65% and 48.5%, respectively. In order to evaluate the accuracy of the TC fusion dataset, this study used a reliable reference dataset, TCCON data, as the verification data. Through comparative analysis, the MAE of the fusion dataset is 0.6273 ppm, RMSE is 0.7683 ppm, and R 2 is 0.8279. It can be seen that the combination of Kriging interpolation and TC algorithm can effectively improve the coverage and accuracy of the XCO 2 dataset. [ABSTRACT FROM AUTHOR]
