class shoot.eddies.track.Tracks(eddies, nback, C=0.07523148148148148, **attrs)[source]#

Collection of eddy tracks over time

Performs eddy tracking on an EvolEddies2D object using the Chelton et al. (2011) algorithm with backward association.

Parameters:

  • eddies (EvolEddies2D) – Detected eddies at multiple time steps.

  • nback (int) – Number of backward time steps for multi-step association.

  • C (float, default 6.5*1e3/86400) – Characteristic velocity scale (m/s).
