Improvement of tracer implementation in martian atmosphere using GCM over HPC cluster

The Martian atmosphere has Carbon Dioxide (CO
₂
) as its main gas comprising of 95.4%. The second main gas is Nitrogen (N
₂
) with 2.7%. All the other gases are in trace amounts, that is they are less than 1% in the atmosphere
^[6]
. Even then these trace gases have a large contribution in the chemical reactions taking place in the atmosphere. These tracer gases are O
₂
, Ozone (O
₃
), Sulfur Dioxide (SO
₂
), Nitrogen Oxide(NO), CO to name a few
^[4]
. General Circulation Models (GCM) are used to simulate the general circulation of the gases in the atmosphere. There are a few GCMs available to study Martian atmosphere. We are using the GCM developed at Laboratory de Meteorologie Dynamique (LMDZ) at France
^[5]
. The aim of this work is to implement SO
₂
tracer species in the LMDZ model. SO
₂
is the most abundant species occurring from the volcanic eruption and contributes to a few percent of the total gases released. SO
₂
can also be obtained by the ultra violet photons from sulphates on the Surface of Mars or dust present in the air. SO
₂
can be one of the effective tracers, ongoing out gassing on Mars.
