Calculate the upward continuation of a potential field grid
Compute the upward continuation of regular gridded data using frequency domain calculations through Fast Fourier Transform.
- Parameters
grid (
xarray.DataArray
) – A two dimensionalxarray.DataArray
whose coordinates are evenly spaced (regular grid). Its dimensions should be in the following order: northing, easting. Its coordinates should be defined in the same units.height_displacement (float) – The height displacement of upward continuation. For upward continuation, the height displacement should be positive. Its units are the same units of the
grid
coordinates.
- Returns
upward continuation (
xarray.DataArray
) – Axarray.DataArray
after upward continuation of the passedgrid
.
