pyacs.lib.euler.vel_from_euler

Horizontal velocity at a point predicted from an Euler pole.

pyacs.lib.euler.vel_from_euler.vel_from_euler(lonp, latp, lon_euler, lat_euler, omega_euler, use_spherical=False)[source]

Return horizontal velocity predicted at a point from an Euler pole.

Parameters:
  • lonp (float) – Longitude of the point where velocity is predicted, decimal degrees.

  • latp (float) – Latitude of the point where velocity is predicted, decimal degrees.

  • lon_euler (float) – Longitude of the Euler pole, decimal degrees.

  • lat_euler (float) – Latitude of the Euler pole, decimal degrees.

  • omega_euler (float) – Angular velocity of the Euler pole, decimal degrees per Myr.

  • use_spherical (bool, optional) – If True, compute site position with a spherical Earth (radius 6371 km) so that pole and site use the same geometry. Default False (ellipsoidal).

Returns:

  • ve (float) – East velocity at (lonp, latp), mm/yr.

  • vn (float) – North velocity at (lonp, latp), mm/yr.
