University of Warsaw Lagrangian Cloud Model

UWLCM is a tool for numerical modeling of clouds using LES model of turbulence and Lagrangian cloud microphysics.

Key features:

• MPDATA algorithm for advection
• Superdroplet or bulk microphysics
• SGS turbulence modeled with Smagorinsky scheme or implicit LES
• models for SGS motion, condensation and coalescence of superdroplets
• 2D or 3D simulations
• superdroplet microphysics can be calculated using GPUs

UWLCM is implemented using the libmpdata++ advection library and libcloudph++ microphysics library.
