Comparative study of the creation, movement, and the various behaviors of dust aerosols between those existing on Earth and on Mars
Summary:
This thesis concerns a comparative study of the creation, movement, and the various behaviors of dust aerosols between those existing on Earth and on Mars. For that purpose, we used the MCD database created by the Dynamic Meteorology Laboratory CNRS in Paris in collaboration with the University of Oxford, the European Space Agency (ESA) and the French National Center for Space Studies (CNES). Using the IDL 8.5 and Panoply programs, we created atmospheric maps for the concentration of aerosols for every season on Mars for the Martian years MY24-MY32, as such we created atmospheric maps for the global concentration of aerosols on Earth.
From the results we concluded that even though Mars has a much thinner atmosphere than of Earth, local winds in Mars can reach the threshold speed that is needed for particles to become airborne and remain suspended in the atmosphere. In addition, the trajectories of the aerosol particles are much longer and the duration that aerosols are suspended in the Martian atmosphere is longer. The lack of precipitation and oceans in Mars combined with the Martian aerosol properties makes it easier for the appearance of global dust storms that engulf the whole planet.
