These visible and thermal infrared images of Yellowstone National park were acquired on July 17, 2021. In the visible image, Landsat 8 channels 4-3-2 are assigned red-green-blue colors (respectively) to simulate natural color. In thermal infrared image, bright pixels are warmer, and dark pixels are cooler. These full satellite images are clipped to the boundaries of Yellowstone National Park.

Yellowstone Caldera Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week’s contribution is from R. Greg Vaughan, research scientist with the U.S. Geological Survey.

There are many satellites that collect data of Earth’s surface and atmosphere, which help us advance our knowledge and understanding of Earth’s interconnected systems. Many of the images acquired by Earth-observing satellites — including those launched and operated by NASA, NOAA, ESA, and the USGS — are freely available to the public. Here, we provide a “how-to” guide for searching, downloading, and viewing satellite data from Yellowstone, using Landsat 8 as an example.

Landsat 8, launched in 2013, is a collaborative mission between
