| Summary: | This study involving both observations and simulations furthers our understanding of water transport in the northern polar region, a critical component of the global water cycle, and explores strengths and weaknesses in simulations of the polar atmosphere. Observations of the northern polar winter by the Mars Climate Sounder onboard the Mars Reconnaissance Orbiter show extensive water ice clouds over the polar ice cap throughout the 300 – 3 Pa (~10 – 50 km) vertical column within the vortex during the entire winter season. The observations also indicate the vortex evolves throughout its depth on a broad range of timescales, from sub-diurnal through seasonal. Time sequences of these data together with results from a Mars global circulation model and EMARS reanalysis (Ensemble Mars Atmosphere Reanalysis System) are used to study the evolution of the winter polar atmosphere and to examine dynamical mechanisms for transporting water across the vortex boundary. Model simulations and reanalysis show similar ... |
