Effect of rain on Thermal Imaging
So, does rain render thermal imaging ineffective? While discussing a SAR search call out, a couple of the guys said it didn't matter I couldn't make it because it was raining (to note: I was the guy with the thermal imagers on my SAR team). Curious, I asked what they meant. They said thermal imagers don't work in the rain, so my toys wouldn't have helped. Surprised by this, I then went and looked online and saw this belief repeated in many places. That somehow rain conceals people from thermal imagers. I understand the thinking. So I decided to shoot a recording and upload it for myth busting. Here's the result at a sub 40millikelvin sensitivity 640 sensor resolution Pulsar Helion XP2 thermal imaging monocular during a rainstorm. Local time 0145 am, temperature 80 degrees F.
