Night Vision Impacts of Climate / Weather / Environment on Outdoor Thermal Imaging Quality

[IR-V]

Below are some thermal images of the same, outdoor view over a period of three summer months, with narrative of the environmental and weather conditions. It is particularly interesting to observe the conditions and thresholds that influence radiance versus reflection of LWIR wavelengths. The time of day is roughly one hour after sunset in each of the thermal images, which is the period following the late day diurnal crossover when absorption of thermal energy from direct, solar radiation has ceased and ambient temperatures have begun to decline.

This is shared in the context of the "weather" thread down below.

You're welcome, MM! Hopefully this will intrigue others into doing the same with their thermal sensors, and this board / forum will become a master repository of the diversity of carefully documented, thermal imaging experiences.

For reference can you give the specs of the thermal device these were taken with? Thanks!

Sure. 17 micron, VOx microbolometer; with 50mm germanium lens.

I don't know what the weather is like in your neck of the woods year round, but I would love it if you could continue these comparisons, especially into winter.

Request acknowledged. If I have the time, I'll assemble some winter images and data, and post them here.
