wradlib.georef.dist_from_orbit

wradlib.georef.dist_from_orbit(pr_alt, alpha, r_pr_inv)

Returns range distances of PR bins (in meters) as seen from the orbit

With PR, we refer to precipitation radars based on space-born platforms such as TRMM or GPM.

New in version 0.10.0.

Parameters:
  • pr_alt (float) – PR orbit height in meters.
  • alpha (numpy.ndarray) – Array of depression angles of the PR beams with shape (nbeams).
  • r_pr_inv (numpy.ndarray) – Array of ranges from ground to PR platform of shape (nbins).
Returns:

ranges (numpy.ndarray) – Array of shape (nbeams, nbins) of PR bin range distances from PR platform in orbit.
