Polar Grid is an NSF MRI funded partnership of Indiana University and Elizabeth City State University to acquire and deploy the computing infrastructure needed to investigate the urgent problems in glacial melting. Polar Grid's major components and concept of operations are depicted in the figure below. A fuller description of the project is available from the full NSF proposal. The Polar Grid project collaborates with CERSER, CReSIS, and the Byrd Polar Research Center. For a list of team members and partners, see Team Members.
