The infrared (IR) camera and hanging sheet setup is an experiment to help visualize the movement of air near the ground surface and the surface of the snow, when present. When recording a video, the IR camera displays the temperature of the thin hanging sheet, which rapidly changes as air moves past it. This visualization can be related to the measurements collected by instruments on the towers to help researchers understand how air moves through the study site.

Michael Haugeneder, a graduate student at the WSL Institute for Snow and Avalanche Research SLF in Switzerland, describes the purpose of the infrared wind sheet and the benefits of gathering this information during the winter.
