TL;DR: In this paper, a method of evaluating systematic errors in measurements of total column dry-air mole fractions of CO2 (XCO2) from space is described, and applied to the v2.8 Atmospheric CO2 Observations from Space retrievals of the Greenhouse Gases Observing Satellite (ACOS-GOSAT) measurements over land.
