Data used to plot figures in the paper "Impacts of Heterogeneous Chemistry on Vertical Profiles of Martian Ozone", by Brown et al.

Observed Vertical Profiles

Files labelled _profiles_ls0-180.dat are the vertical profile observations from the NOMAD spectrometer suite aboard the ExoMars Trace Gas Orbiter (TGO), which include the variable in parts per million by volume, the altitude, and solar longitude. Data are from Mars Year 35, Ls = 0 -180. NPH and SPH are the North and South Polar Hood respectively, and refer to observations >45 N/S. For more information, the ozone, water ice, and water vapour data have been processed in the same way as described by Patel et al. (2021), Liuzzi et al. (2020), and Villaneuva et al. (under review) respectively.

1-D Model

Netcdf files are outputted from the 1-D Mars Photochemical Model (1-D MPM), which is extracted from the Open University Mars Global Climate Model. The model is compiled with 70 vertical layers (sigma). File names are formatted by:


[run number]_[heterogeneous status]_[latitude]_[sol]_100.nc

  • heterogeneous status:
  1. ihc = improved heterogeneous chemistry
  2. nhc = no heterogeneous chemistry

The figure to compare between the original heterogeneous scheme and the one used in the paper are given by s30_comp_lat0.nc and s30_het_lat0.nc respectively.
