Atmospheric CO 2 volume mixing ratios retrieved by the AIRS and SCIAMACHY instruments, are compared over North America during the summer and autumn of 2003. Examination of the deviations of the CO 2 volume mixing ratios, relative to the mean CO 2 background measured by each instrument, reveal large‐scale coincidental spatial features that develop over the course of the year. Furthermore, the time series of the monthly CO 2 anomalies show a seasonal cycle signal that is characteristic of the upper and lower troposphere to which AIRS and SCIAMACHY are respectively sensitive to. This comparison demonstrates that there is a general consistency between the CO 2 distributions retrieved by AIRS and SCIAMACHY, when considering the different vertical sensitivities of the instruments.
