Abstract : SIRS-A satellite radiance measurements and correlated radiosonde temperature and dew point temperature profiles were used to determine the variability of atmospheric CO2 for different altitudes, by asymptotic solution of the Ladenberg-Reiche equation. The 17 different sets of data used in these calculations were characterized by clear weather conditions and low water vapor content. Transmittances used in the retrieval were corrected using the measured temperature and dew point temperature profiles. The results indicate that the atmospheric CO2 mixing ratio varies temporally and spatially by 10% or more. The derived CO2 profiles over the central United States are distinctly different from those determined for the South Pacific region.
