Research on the influence of the vertical temperature profile on the retrieval of CO2 concentration

The growth of the concentration of CO 2 results in the global warming. The atmospheric temperature can impact the intensity and the shape of line of the molecular absorption spectrum of CO 2 , so that the atmospheric vertical temperature profile changes affect the measured absorption spectrum of CO 2 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 CO 2 concentration. The simulation results suggested that the error of retrieving CO 2 concentration caused by the vertical temperature profile changes in the upper layers was much less than 1%.
