The Phoenix Mars Lander observed this type of cloud, which absorb outgoing infrared   radiation but fail to deflect incoming sunlight, leading to a net heating effect.
The Phoenix Mars Lander observed this type of cloud, which absorb outgoing infrared   radiation but fail to deflect incoming sunlight, leading to a net heating effect. They can  originate from the glaciation of other clouds, and (*) jet contrails are a man-made form of these  clouds. They are generally found in the upper atmosphere and are often associated with fair  weather. For 10 points, identify this wispy type of cloud made of ice crystals.
