Python Cloud Large Eddy Simulation, or PyCLES (pronounced pickles), is a massively parallel anelastic atmospheric large eddy simulation infrastructure designed to simulate boundary layer clouds and deep convection. PyCLES is written in Python, Cython, and C. It was primarily developed by Kyle Pressel and Colleen Kaul as part of the Climate Dynamics Group at both the California Institute of Technology and ETH Zurich.

The model formulation is describe in detail in:
