Introduction:
Recently, [1] Characterized The Relation Between
Ozone And Water Vapor Using Spicam Simultaneous
Measurements Of O3 And H2o Column Densities Covering Four Martian Years. They Found That O3 And
H2o Columns Are Clearly Anti-Correlated At High Latitudes While Being Uncorrelated At Low Latitudes.
In Our Study, We Take Advantage Of The Nomad
Capability To Measure Simultaneous Vertical Profiles
Of Ozone And Water Vapor To Characterize The O3 –
H2o Relationship At Different Altitude Ranges And Latitudes.
