Use data from any (curvilinear) grid

Parcels works on model outputs including NEMO, POP, MITgcm, and more.

Combine data on different grids

Create a single Parcels FieldSet from multiple different model outputs.

Define and execute custom kernels

Encode custom particle operations such as swimming or sinking.

Advect particles in 2D and 3D

Use built-in kernels for Runge-Kutta4 and Runge-Kutta45 schemes.

Diffuse particles in 2D

Use built-in kernels for the Milstein and Euler-Maruyama schemes.

Start and stop particles during execution

For example, to simulate oil spills or fish spawning.

Simulate particle-particle interactions

For example, to simulate aggregation or mortality.

Output particle data in zarr format

For highly efficient output of particle data.
