metric_to_angular#
When calculating FSLE or FTLE grids, if the velocity fields are expressed in
m/s
, the program metric_to_angular.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

Usage#
usage: metric_to_angular [-h] [--mask MASK] src dst u v
Convert the U and V components speeds from metric to angular system units
positional arguments:
src Directory containing the NetCDF grids to convert
dst Directory containing the NetCDF grids converted
u NetCDF variable containing the U component
v NetCDF variable containing the V component
options:
-h, --help show this help message and exit
--mask MASK Select only the files matching the mask
