Acknowledging the support of NCAR and CISL computing when you publish research results helps ensure continued support from the National Science Foundation and other sources of funding for future high-performance computing (HPC) systems. It is also a requirement of receiving an allocation, as noted in your award letter.
The reporting requirements, how to cite your use of various systems, and recommended wording of acknowledgments can be found on
this CISL web page. The content of citations and acknowledgments varies depending on the type of allocation that was awarded.
