mpas_tools.transects.angular_distance(x, y, z)[source]¶

Compute angular distance between points on the sphere, following: https://en.wikipedia.org/wiki/Great-circle_distance

Parameters:

x (numpy.ndarray) – The Cartesian x coordinate of a transect, where the number of segments is len(x) - 1. x, y and z are of the same lengt.
y (numpy.ndarray) – The Cartesian y coordinate of the transect
z (numpy.ndarray) – The Cartesian z coordinate of the transect

Returns:

distance (numpy.ndarray) – The angular distance (in radians) between segments of the transect.
