Cheyenne is being retired on December 31, 2023. As of this week, only two months remain to switch all projects from Cheyenne to Derecho. Make it a priority to transition your computing projects to Derecho as soon as possible, to avoid needing to repeat important runs. CISL cannot provide anyone with special priority to complete last-minute work, so consider it imperative to switch at the next ...

Explore a Rich New Dataset on Long-Term U.S. Weather Patterns

October 25, 2023

Researchers can now access CONUS404, a remarkable new dataset on U.S. weather patterns, through the Casper analysis cluster. The nearly one-petabyte dataset is the result of a collaboration between the National Center for Atmospheric Research (NCAR) and the U.S. Geological Survey (USGS) and was recently published in NCAR’s Research Data Archive (RDA). The CONUS404 dataset covers the contiguo...
