Stability of Subsurface Carbon Dioxide Ice over the Obliquity Cycle

Carbon dioxide (CO2) ice does not remain stable at the surface of Mars for long periods of time over the obliquity cycle. We use the UK version of the LMD Mars Global Circulation Model (MGCM) [1] with a newly integrated subsurface scheme to investigate how the timescales for the stability of CO2 ice...

Description
Summary:Carbon dioxide (CO2) ice does not remain stable at the surface of Mars for long periods of time over the obliquity cycle. We use the UK version of the LMD Mars Global Circulation Model (MGCM) [1] with a newly integrated subsurface scheme to investigate how the timescales for the stability of CO2 ice are affected by overlying regolith at different obliquities within the range expected for Mars over the last 4 Myrs [2]
