metric_to_angular

When calculating FSLE or FTLE grids, if the velocity fields are expressed in “m/s,” the program “map_of_fle. py” must make a change of reference in order to calculate how many degrees the particle has been moved.

To avoid this costly conversion in terms of computation time, run this program to change the unit of grids at the input from “m/s” to “degrees/s.”

Type metric_to_angular.py --help to see the available options.
