Looking back on Cheyenne’s seven years

January 22, 2024

From January 2017 to December 2023, the NSF NCAR supercomputer Cheyenne advanced all aspects of Earth systems science.

Though slated to retire in 2021, Cheyenne was called upon to serve longer due to the effects of the pandemic. 

Learn more about Cheyenne, its history, and the many ways it underpinned scientific progress and policy—from helping identify climate patterns that unfolded over decades to illuminating the atmospheric impacts of wildfire emissions. 

Read this Cheyenne retrospective to gain insight into what NSF NCAR Director Everette Joseph has called “a special machine.”
