wradlib.georef.satellite.dist_from_orbit¶
- wradlib.georef.satellite.dist_from_orbit(sr_alt, alpha, beta, r_sr_inv, re)¶
Returns range distances of SR bins (in meters) as seen from the orbit
With SR, we refer to precipitation radars based on space-born platforms such as TRMM or GPM.
- Parameters:
sr_alt (
float
) – SR orbit height in meters.alpha (
numpy.ndarray
) – Array of local zenith angles of the SR beams with shape (nscans, nbeams).beta (
numpy.ndarray
) – Off-Nadir scan angle with shape (nbeams).r_sr_inv (
numpy.ndarray
) – Array of ranges from ground to SR platform of shape (nbins).re (
float
) – earth radius [m]
- Returns:
ranges (
numpy.ndarray
) – Array of shape (nbeams, nbins) of PR bin range distances from SR platform in orbit.
