Ground-based remote sensing of O₃ by high- and medium-resolution FTIR spectrometers over the Mexico City basin

We present atmospheric ozone (O₃) profiles measured over central Mexico between November 2012 and February 2014 from two different ground-based FTIR (Fourier transform infrared) solar absorption experiments. The first instrument offers very high-resolution spectra and contributes to NDACC (Network for the Detection of Atmospheric Composition Change). It is located at a mountain observatory about 1700 m above the Mexico City basin. The second instrument has a medium spectral resolution and is located inside Mexico City at a horizontal distance of about 60 km from the mountain observatory. It is documented that the retrieval with the high- and medium-resolution experiments provides O₃ variations for four and three independent atmospheric altitude ranges, respectively, and the theoretically estimated errors of these profile data are mostly within 10 %. The good quality of the data is empirically demonstrated above the tropopause by intercomparing the two FTIR O₃ data, and for the boundary layer by comparing the Mexico City FTIR O₃ data with in situ O₃ surface data. Furthermore, we develop a combined boundary layer O₃ remote sensing pro ... mehr
