### Uncertainty along trajectory endpoint

Posted:

**August 31st, 2018, 3:47 am**Hi all,

For the purpose of a particular study (trajectory analysis by eg PSCF), I was wondering if I could implement uncertainty to the backtrajectory's endpoints coordinates. I figured that this uncertainty should increase with time so that it could account a little bit for dispersion.

So, for each endpoint, I have made a resample of 1000 points, with a 2-D Gaussian noise centered at the endpoint's coordinate, and where the width of the cumulative probability function increases with time (around 0.025 x i, where i is time). An output of this approach is enclosed hereinbelow.

So my question is: do you guys feel that this can make some sense ?

Best,
