Reflectivity-and commonly, the word reflectance-refers to the amount of incident radiant energy is mirrored or reversed from a material surface.
A bolometer is a sensor physically much like a common photographic CMOS or CCD sensor, except that it employs a different transduction process and is sensitive to a very broad range of electromagnetic energy
The effects of atmospheric media on thermography will be dependent upon its temperature, density, movement, particulates, etc.
The baseline and responsive documentation-and immediate dissemination-of technical (aerial, hyperspectral, etc.) imagery of flooding is tremendously practical.
There is no excerpt because this is a protected post.
The images below represent some interesting results from both vertical (orthogonal) and oblique aerial thermography throughout 2018.
