It's looking a little cloudy today

Simulations on supercomputers inform stakeholders about infrastructure investments needed to deal with the consequences of global climate change. The Community Atmosphere Model–Spectral Element simulates long-term global climate. Improved atmospheric modeling under Titan will help researchers better understand future air quality as well as the effect of particles suspended in the air. The new Titan system will be able to simulate from one to five years per day of computing time, up from the three months or so that Jaguar was able to churn through in a day.
