This dataset contains NOMAD UVIS retrievals of O3 number density as published in Khayat et al. (2021), and colocated GEM-Mars GCM simulated O3 number densities. These data are used in the model-data comparison in the Khayat et al. (2021) paper. The text file has 4 columns: 1) unique NOMAD observation file ID, 2) counter for the vertical levels in the various profiles, 3) retrieved O3 number density, 4) simulated O3 number density. Geometrical information for the profile times and locations can be found in Khayat et al. (2021) and references therein, in particular Patel et al. (2021) and Patel (2021).

The GEM-Mars model and the simulation used for this dataset was published in Daerden et al. (2019).
