Outline of Final Research Achievements |
To clear up riddles of the Venusian atmosphere, we performed ground-based IR spectroscopic observations. The largest dynamical issue is the “Super Rotation” of the atmosphere. The atmosphere is rotating 60 times faster than the solid body. By picking up atmospheric waves from spectra, we tried to understand the acceleration mechanism of the Super Rotation. The largest chemical issue is “Stability of the CO2 atmosphere”. The process for CO2 to be kept at 96% has not been understood. By using spectroscopic observations, we measured HCl and CO abundances, and then investigated catalytic reaction cycles to reproduce CO2.
