The department includes a powerful computing environment with a network of more than 150 workstations and more than 20 terrabytes of local disk storage. Department scientists use several computer clusters with more than 1000 processors maintained by the Center for High Performance Computing to run various state-of-the-art regional and global atmospheric models. Classroom facilities include the Meteorology Computation and Visualization Laboratory that features workstations for each individual student. Over 10 GB of real-time meteorological data are downloaded and processed by the department each day to support its research and teaching missions, including numerical model, satellite, radar, and surface and upper-level data. The department also includes laboratory facilities in cloud physics and atmospheric chemistry, the Cooperative Institute for Regional Prediction, and a real-time mesoscale observation network.
