Short summary

An algorithm for retrieval of vertical profiles of CO₂ from ground-based spectra is described. Retrieval of CO₂ vertical profiles from would be very beneficial for carbon cycle studies and the validation of satellite measurements. There are approximately 3 degrees of freedom for the CO₂ profile. The accuracy of retrievals of CO₂ from the spectral band used is limited by small errors in the calculated spectrum. Ongoing research is needed and described.
