Global Cloud-system-resolving Model Simulation

A snapshot from a global cloud-system-resolving model simulation for the period May 21 to Aug. 31, 2009, showing a sector of the Earth that includes eastern Asia and the western tropical Pacific Ocean. Cloudiness (based on outgoing, long-wave radiation) is in shades of gray and the precipitation rate is in rainbow colors.

This image was taken as part "Project Athena: High-resolution Global Climate Simulations," which explicitly modeled cloud systems, featured hundreds of weather prediction model simulations that sought to replicate the climate of the late 20th century, and to predict the impact of CO2 emissions on the Earth's climate in the final decades of the 21st century. Researchers aimed to prove that enhanced resolution in climate simulations increases the accuracy of climate models. The project was supported by the National Science Foundation (grants AGS 08-30068 and AGS 09-57884).
