pyrcel: cloud parcel model

DOIPyPI versionBuild StatusDocumentation StatusCode Style

This is an implementation of a simple, 0D adiabatic cloud parcel model tool (following Nenes et al, 2001 and Pruppacher and Klett, 1997). It allows flexible descriptions of an initial aerosol population, and simulates the evolution of a proto-cloud droplet population as the parcel ascends adiabatically at either a constant or time/height-dependent updraft speed. Droplet growth within the parcel is tracked on a Lagrangian grid.


You are invited to use the model (in accordance with the licensing), but please get in touch with the author via e-mail or on twitter. p-to-date versions can be obtained through the model’s github repository or directly from the author. If you use the model for research, please cite this journal article which details the original model formulation:
