Introduction:
The Nomad-Uvis Instrument On Board The
Exomars Trace Gas Orbiter Has Been Investigating
The Martian Atmosphere With The Occultation Technique Since April 2018 (Vandaele Et Al. 2015). In The
Solar Occultation Mode, It Is Mainly Devoted To Study
The Climatology Of Ozone And Aerosols Content (Patel
Et Al. 2021; Khayat Et Al. 2021). Here, We Will Present An Inter-Comparison Of Retrieval Codes For Ozone
Observed With Nomad-Uvis.
Nomad-Uvis Solar Occultations:
We Analyzed Almost Two Mars Years Of Ozone
