Nighttime Water Ice Clouds Predicted by Models are Confirmed by MCS Observations
Posted 2011/10/25 12:00 CDT | 0 comments
A daily cycle of cloud formation in the Martian tropics during northern summer is driven largely by solar radiation and the associated solar thermal tide. Models predict a striking pattern of cloud formation above the high altitude volcanoes of the Tharsis region. At mid-day, the atmosphere is typically free of clouds due to elevated temperatures. Beginning in the early evening hours, atmospheric cooling at altitudes above 20 kilometers begins to foster water ice cloud formation. During the night, the altitude of cloud formation descends closer to the surface.

Asteroid 2012DA14 was a close one.
It missed us. But there are more out there.
