Possibility to use the library for a backtracking analysis.

[Schimidel]

I am interested in backtracking the trajectory of plastic particles in the ocean. Does this library allow me to track the origin of plastic based on ocean current and wind data?

Hi @Schimidel, apologies for the delay in response, I was on a boat doing measurements! In essence, you can use plasticparcels for backtracking problems, all you need to do is reverse the sign of the integration (using a negative value for dt, see this parcels tutorial for more info on that.

With ocean currents and wind, the problem is (mathematically) reversible, but if you'd like to include the effects of things like biofouling, or some stochastic parameterisation for vertical mixing, you can no longer simply reverse the sign.

Let me know if you have any questions!
