CESM – Modeling Earth Future Climate

CESM - High Level Component Diagram

Following the previous post, it is clear why climate modeling is performed using computers. The amount of data and computational needs of climate simulations can be significant, so supercomputers are extensively used to perform the task. In fact, THE strongest
