Drops (name of a candy in Polish) is a simple yet robust numerical model of cloud drop formation on aerosol particles. Using atmospheric physics nomenclature, it's an adiabatic air-parcel model employing the moving-sectional representation of particle size spectra. Drops is a research project that have been developed at the Institute of Geophysics, University of Warsaw with funding from the EU's EUCAARI project (European Integrated Project on Aerosol Cloud Climate Air Quality Interactions). Drops uses a novel approach for solving aerosol growth equation. The theory behind the model as well as some aspects of its implementation are described in a paper published in the "Geoscientific Model Development Discussion" journal:

The source code and a manual of Drops (version 1.0) was released under the GNU GPL license and was published as an electronic supplement of the above mentioned paper:

Drops is written in C++ employing the Boost.units framework for dimensional analysis of source code at compilation time. Drops uses the CVODE solver for solving systems of partial differential equations.
