CISL Director's Office

The Director's Office of the Computational and Information Systems Laboratory (CISL) at the National Center for Atmospheric Research (NCAR) works to ensure that geoscientists have a balanced mix of computational resources to study the complex processes that make up the Earth system, from the ocean floor and atmosphere to the Sun's core.

These computational resources include high-performance computers, high-speed networks, a world-class data archiving and storage facility, research data sets, state-of-the-art knowledge environments and visualization technologies, advanced mathematical tools, and a staff of professionals dedicated to advancing Earth systems science across broad fronts.
