Water loss during the Mars Year 34 C Storm Journal Article uri icon

Overview

abstract

  • ; Lower atmosphere variations in the martian water vapour and hydrogen; abundance during the Mars Year (MY) 34 C storm from; L; S; =326.1; ◦; -333.5; ◦; and their associated effect on hydrogen escape are investigated using a; multi-spacecraft assimilation of atmospheric retrievals into a Martian; global circulation model. Elevation of the hygropause and associated; increase in middle atmosphere hydrogen at the peak of the MY 34 C storm; led to a hydrogen escape rate of around 1.4×10; 9; cm; −2; s; −1; , meaning the MY 34 C storm; enhanced water loss rates on Mars to levels observed during global-scale; dust storms.; The water loss rate during the MY 34 C storm (a loss of 15% of the; total annual water loss during only 5% of the year) was three times; stronger than the weak MY 30 C storm assimilation, demonstrating that; interannual variations in C storm strength must be considered when; calculating the integrated loss of water on Mars.;
