NSF NCAR relies on its Derecho supercomputer, orchestrated by Altair PBS Professional, to generate twice-daily weather forecasts for Antarctica’s McMurdo Station. Extreme conditions make accurate forecasting essential for protecting researchers and supporting scientific missions. The Antarctic Mesoscale Prediction System processes massive datasets using high-performance computing to model rapidly changing weather patterns. PBS Professional ensures efficient workload scheduling and system utilization. The system enables safe travel, operational planning, and uninterrupted research in one of the world’s harshest environments. These forecasts play a critical role in advancing polar science while safeguarding personnel and infrastructure in Antarctica.
