During a recent visit to Waterville Valley, New Hampshire, I had the chance to capture some thermal video of snowmaking operations at their new tubing facility. The year-round resort, located about 90-minutes north of ITC’s Boston-Regional Training Center, is a popular ski and snowboarding destination in New England. It’s been a pretty good year for natural snow here in the northeast, but even then many resorts still rely on artificial snowmaking to help supplement what Mother Nature provides.
The air temperature was only about 10˚F (-12˚C) in this situation. Given the conditions, the water supply ends up looking quite a bit warmer relative to the surrounding environment. This gives it the appearance of being warm when it’s really not. That’s because the upper span limit of my imager was set to approximately 25˚F (-4˚C). Anything near that threshold shows up as yellow or white “hot” on the color scale in the thermal video.
