Retrieval of xCO 2 from ground-based mid-infrared (NDACC) solar absorption spectra and comparison to TCCON
High-resolution solar absorption spectra, taken within the Network for the Detection of Atmospheric Composition Change Infrared Working Group (NDACC-IRWG) in the mid-infrared spectral region, are used to infer partial or total column abundances of many gases. In this paper we present the retrieval o...
