Mars upper thermosphere CO2 density and temperature vertical profiles retrieved from NOMAD-SO diffraction order 165

Vertical profiles of carbon dioxide and temperature in Mars upper atmosphere retrieved by the Royal Belgian Institute for Space Aeronomy from diffraction order 165 of the SO channel of the NOMAD instrument on board ESA’s ExoMars Trace Gas Orbiter.
These measurements were performed by solar occultation by Mars atmosphere.
The temperature profiles are derived from the carbon dioxide density profiles with the hydrostatic equilibrium equation.
Those profiles extends from around 140 km to 190 km altitude depending on the seasons at Mars.
The corresponding uncertainties, solar longitudes, local solar times, latitudes and longitudes are also provided within this archive.
