DOI: 10.1007/s11356-021-17139-5
Abstract: Atmospheric CO2 anomaly (△XCO2) is essential in evaluating regional carbon balance. However, it is difficult to understand △XCO2 variation characteristics due to regional differences. This paper explored the inter-annual and inter-monthly variation patterns of △XCO2… read more here.

DOI: 10.1109/tgrs.2023.3238117
Abstract: Carbon observation satellites based on passive theory (e.g., OCO-2/3, GOSAT-1/2, and TanSat) have relatively high carbon dioxide column concentration (XCO2) accuracy when the observation conditions are met. Passive satellites have data bias and coverage deficiencies… read more here.
