- GeorefMethods.correct_parallax(drt, **kwargs)#
Adjust the geolocations 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.
- Parameters:
obj (
xarray.Dataset)drt (
float) – Gate lenght of SR in meter.
- Returns:
obj (
xarray.Dataset) – obj with added coordinates in ground radar projection and range
