What infrared monitoring can teach us about Yellowstone National Park

By: - 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: - 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 […]

We do not define the habitat of […]
