Validation of GOSAT and OCO-2 against In Situ Aircraft Measurements and Comparison with CarbonTracker and GEOS-Chem over Qinhuangdao, China

Farhan Mustafa et al.

Summary: In this study, aircraft measurements were conducted to validate the accuracy of CO2 retrievals from two satellites. The comparison with in situ measurements and model datasets showed good agreement among the datasets. The biases in dry-air column-averaged CO2 mole fractions retrieved from OCO-2 and GOSAT were also reported.
