Short summary
We present a new numerical code to retrieve NO2 vertical column densities (VCDs) and concentrations from previously retrieved slanted columns from spectroscopic measurements in the visible and ultraviolet spectral ranges in different vertical viewing directions. We use this code on 1.5 years of data from a measurement station located in the south of Mexico City and compare daily and monthly averages to averages of in situ measurements. We show daily NO2 VCD time series for a few example days.
