Since the elaboration of the COSPAR Mars International Reference Atmosphere (MIRA) in 1982, our knowledge of the Martian atmosphere and its main (CO2, dust, water) cycles has been greatly improved. This is firstly due to the recent continuous multi-annual observations gathered by instruments on board the Mars Global Surveyor, Mars Odyssey, Mars Express and Mars Reconnaissance Orbiter spacecrafts. The development of models capable of matching these observations have also contributed to better understand the physical processes at work on Mars. At the COSPAR 2014 scientific assembly, we will address revisiting MIRA and assess on possible ways of updating it to match our current knowledge of the Martian atmosphere.
