Lagrangian Time and Space Scales

The Lagrangian autocorrelation function was computed for each drifter velocity component, and then integrated from zero lag to the first zero crossing of the autocorrelation to give a Lagrangian integral time scale. The Lagrangian space scale was then found by multiplying the integral time scale by the rms velocity for each component.
