CLEO is a library for Super-Droplet Model (SDM) cloud microphysics. SDMs are Lagrangian particle
models in which the evolution of cloud droplets is represented by so-called “super-droplets” developed by MPI-M.

The recently established Super-Droplet Model (SDM) is a promising alternative to conventional bulk and bin models for cloud microphysics. Briefly, SDM replaces traditional modelling of condensate distributions with Lagrangian particles, so called ‘Super-Droplets’, that act as representatives for the condensate populations of a cloud.
