- wradlib.georef.satellite.correct_parallax(sr_xy, nbin, drt, alpha)¶
Adjust the geo-locations of the SR pixels
With SR, we refer to precipitation radars based on space-born platforms such as TRMM or GPM.
The sr_xy coordinates of the SR beam footprints need to be in the azimuthal equidistant projection of the ground radar. This ensures that the ground radar is fixed at xy-coordinate (0, 0), and every SR bin has its relative xy-coordinates with respect to the ground radar site.
numpy:numpy.ndarray) – Array of parallax corrected coordinates of shape (nscans, nbeams, nbins, 2).
numpy:numpy.ndarray) – Array of ranges from ground to SR platform of shape (nbins).
numpy:numpy.ndarray) – Array of SR bin altitudes of shape (nscans, nbeams, nbins).
