geocat.comp.gradient.gradient

geocat.comp.gradient.gradient(data)

Extract and return the gradient values of a dataset at each point in the dataset. Assuming that the data points are on the surface of the WGS84 ellipsoid.

Parameters

data (numpy.ndarray, xarray.DataArray) – n-dimensional dataset, with orthographic latitude longitude coordinates

Returns

gradients (list of numpy.ndarray, list of xarray.DataArray) – longitudinal and latitudinal gradients calculated using th WGS84 geoid.
