Abstract

The growth of the concentration of CO₂ results in the global warming. The atmospheric temperature can impact the intensity and the shape of line of the molecular absorption spectrum of CO₂, so that the atmospheric vertical temperature profile changes affect the measured absorption spectrum of CO₂ by the satellite. This study focuses on the influence of the vertical temperature profile changes at different latitudes and the discontinuity of the profile in the upper layers of the atmosphere on the accuracy of retrieving CO₂ concentration. The simulation results suggested that the error of retrieving CO₂ concentration caused by the vertical temperature profile changes in the upper layers was much less than 1%.
