CCSM4 T31 Preindustrial Control

The low-resolution version of the Community Climate System Model, version 4 (CCSM4) is a computationally efficient alternative to the intermediate and standard resolution versions of this fully coupled climate system model. It employs an atmospheric horizontal grid of 3.75 x 3.75 degrees and 26 levels in the vertical with a spectral dynamical core (T31) and an oceanic horizontal grid that consists of a nominal 3 degree resolution with 60 levels in the vertical. This low-resolution version (T31 x 3) can be used for a variety of applications including long equilibrium simulations, development work, and sensitivity studies. 1

The simulation available here is the CCSM4 T31 preindustrial control simulation, and is documented in the reference publication cited below.
