The UCLA Large Eddy Simulation Code (UCLALES)
The UCLA Large Eddy Simulation code is the working horse of our research group. Developed since the mid-nineties by Bjorn Stevens, the code is specifically designed for detailed studies of cloud dynamics. The code is highly parallelized, and includes advanced radiation and cloud/rain microphysical schemes. The code is always under development, both in terms of bug fixing as well as in terms of addition of new features.
UCLALES is freely available and licensed under GPLv3; see the Download section for instructions. If you are interested in using the code, it is appreciated (and highly recommended) to keep in touch with the developers (
thijs.heus@zmaw.de) about new versions, limitations and bug fixes.
In November 2011, an internal course on the use of UCLALES was held. The handouts of this course can be found 
over here.

Some simulations that were recently performed with UCLALES give a good overview of what is currently possible with the code.
Stratocumulus to cumulus transition
Irina Sandu performed simulations of the transition of stratocumulus to shallow cumulus clouds. She now leads a GCSS intercomparison study on this transition.
Cumulus in a warmer climate
Malte Rieck studied what happened to trade wind cumuli (as studied in the RICO field campaign and intercomparison study) in a 2K warmer climate.
