Differences in spatial correlation coefficients between a high resolution regional scale simulation and observations (top) as well as between a coarse resolution global scale simulation and observations (bottom). Cross hatching indicates that the differences are statistically significant. Image courtesy Jiali Wang; click to view larger.
New methods for identifying value added by a regional climate model

In a paper published in the Journal of Geophysical Research – Atmospheres, researchers identified the value added by a regional climate model - which addresses a long-standing question in the scientific community on the utility of downscaling.

This image shows what happens in a detector after colliding two protons, each with an energy of roughly 50 TeV.  This single collision event was taken 
from a simulation of roughly 400 million events. Blue lines represent the tracks of charged  particles, red lines represent electrons and muons. Yellow cones represent hadronic jets with energies above 3 TeV. Image by Sergei Chekanov; click to view larger.
Researchers create enormous simulation of proton collisions

Scientists from Argonne and the University of Chicago have created one of the world's largest samples of Monte Carlo simulated proton-proton collisions. The data sample contains 400 million events, each of which contains 5500 particles on average, totaling more than 2 trillion generated particles.
