NASA’s Global Modeling and Assimilation Office (GMAO) is located at the Goddard Space Flight Center in Greenbelt, Maryland. The office’s mission is to “maximize the impact of satellite observations on analyses and predictions of the atmosphere, ocean, land, and cryosphere.” One of the GMAO’s activities is to use the data from over 5,000,000 observations acquired every six hours to predict weather ...and model climate on a global scale. The global surface area of Earth is 510,072,000 km square (196,939,900.212 mi square) with water covering 70.8 percent and land taking up 29.2 percent. Predicting weather and modeling climate at these scales takes a lot of computing power provided by NASA Goddard’s Computational and Information Sciences and Technology Office (CISTO). The latest addition to NASA’s Discover supercomputing cluster is based on Intel® Xeon® Gold 6148 processors interconnected by Intel® Omni-Path Architecture (Intel® OPA) fabric.
