The EPIC data also helped confirm that the flashes are coming from a high altitude, not simply water on the ground. Two channels on the instrument are designed to measure the height of clouds. According to the observations, high cirrus clouds—5 to 8 kilometers (3 to 5 miles) up in the atmosphere—appeared wherever the glints were located.
“The source of the flashes is definitely not on the ground,” Marshak said. “It is definitely ice, and most likely solar reflection off of horizontally oriented particles.”
Marshak is now investigating how common these horizontal ice particles are, and whether they are common enough to have a measurable impact on how much sunlight passes through the atmosphere. If so, it is a feature that would need to be incorporated into computer models of how much heat is reaching and leaving Earth.
Perhaps we should admit that it will take time to get ‘the science’ properly settled.
There is a notion in IPCC ‘climate science’ that high altitude cloud has a warming influence on the surface. A manurial notion if ever there was one.
As to whether there will be ice cloud at elevation or not….then the ozone content of the air will be a factor of importance because ozone absorption of infrared from the Earth itself determines air temperature and therefore relative humidity and the degree and extent of precipitation.
