+## NSF NCAR Derecho
+
+NCAR's Derecho supercomputer is a high-performance computing system with 19.87 petaflops of processing power. It comprises 2,488 nodes, each equipped with two 64-core AMD EPYC 7763 Milan processors, totaling 323,712 processor cores. Each node has 256 GB of DDR4 memory and is interconnected by an HPE Slingshot v11 high-speed network in a dragonfly configuration. The system supports Earth system science research for U.S. institutions.
+
+### Use Cases:
+- **Earth System Science Research:** Designed specifically for tasks related to climate modeling, weather prediction, and environmental studies.  
+- **Large-Scale Simulations:** Optimal for computationally demanding research in Earth sciences that requires extensive core-hours.  
+- **Educational Use:** Available for classroom and instructional purposes, supporting students, postdocs, and new faculty without external funding.
