What infrared monitoring can teach us about Yellowstone National Park
By: R. Greg Vaughan - August 30, 2022
Thermal infrared satellite images are an important volcano monitoring tool that can be used to estimate surface temperature. And, in fact, these data are freely available for Yellowstone and many other volcanoes worldwide! But interpreting these images is not as straightforward as it might seem—what shows up as either hot or cold depends on a […]
Scientists discover new thermal areas in Yellowstone National Park
By: R. Greg Vaughan - April 4, 2022
On the North side of the Mallard Lake resurgent dome there are several isolated thermal areas that were recently mapped using high-resolution visible satellite and aerial data. These are not new thermal areas like the one near Tern Lake; instead, they have been there for decades but eluded our thermal-area mapping—until now. In Yellowstone, thermal […]

Yes, some of Yellowstone’s thermal areas are cool—as in, no longer hot. Cooling is part of the “life cycle” of a thermal area. And, just as it’s important to keep track of where thermal areas warm up, it’s also important to keep track of where they are cooling down. We do not define the habitat of […]
