-Welcome to the documentation of Parcels. **Parcels** (Probably A Really Computationally Efficient Lagrangian Simulator) is a set of Python classes and methods to create customisable particle tracking simulations using output from Ocean Circulation models. Parcels can be used to track passive and active particulates such as water, plankton, `plastic <http://www.topios.org/>`_ and `fish <https://github.com/Jacketless/IKAMOANA>`_.
