Who can make available to me an attenuation curve for infrared radiation in normal atmospherical environment?
Thanks in advance.

I have performed IR thermography on supercell thunderstorm cloud bases and tornadoes which are at a significant distance from the camera. I will assume you are using microbolometer-based imager(s). We established through references that temperature estimation through thermographic radiance measurements is reliable out to about 3 kilometers. Attenuation becomes very significant there and increases to complete unreliability at 5 kilometers. We were operating in conditions where the dewpoint was around 19 degrees C. As the dewpoint increases above 22 degrees C., the reliability zone will decrease from these shared here.
I hope this helps! |

| Here is the IR of the same shot. |
