Bases:
object
wradlib xarray SubAccessor methods for Georef Rect Methods.
- xyz_to_spherical(**kwargs)[source]#
Returns spherical representation (r, theta, phi) of given cartesian coordinates (x, y, z) with respect to the reference altitude (asl) considering earth’s geometry (crs).
- Parameters
obj (
xarray.DataArray
|xarray.Dataset
)- Keyword Arguments
crs (
osgeo.osr.SpatialReference
) – projection of the source coordinates (aeqd) with spheroid model defaults to None.ke (
float
) – Adjustment factor to account for the refractivity gradient that affects radar beam propagation. In principle this is wavelength- dependend. The default of 4/3 is a good approximation for most weather radar wavelengths
- Returns
obj (
xarray.Dataset
) – obj with added spherical coordinates.
