wradlib.ipol.cart_to_irregular_spline

wradlib.ipol.cart_to_irregular_spline(cartgrid, values, newgrid, **kwargs)

Map array values defined by cartesian coordinate array cartgrid to new coordinates defined by newgrid using spline interpolation.

Keyword arguments are fed through to scipy.ndimage.map_coordinates

Parameters

  • cartgrid (numpy ndarray) – 3 dimensional array (nx, ny, lon/lat) of floats

  • values (numpy 2d-array) – 2 dimensional array (nx, ny) of data values

  • newgrid (numpy ndarray) – Nx2 dimensional array (…, lon/lat) of floats

  • kwargs (scipy.ndimage.map_coordinates) –

Returns

interp (numpy ndarray) – array with interpolated values of size N
