Infrared
Analysis
When
an IR pass filter is applied to the photograph, several darker sections
appear that are not easily seen in the original photograph.
The
darker regions would represent cooler sections within the photograph.
The amount of thermal emission from the darker areas are dependant
on their size, their emission and their temperature.
Gauging
from the temperatures of the surrounding structures, it is estimated
that the darker areas of the "cloud" are 10 to 15 degrees
cooler than the surrounding ambient air temperature.
It
should be noted that the estimate of temperature variance is based
solely upon the analysis of the photograph.
