Kriging spherical model
Webvariogram_model (str or GSTools CovModel, optional) – Specifies which variogram model to use; may be one of the following: linear, power, gaussian, spherical, exponential, hole-effect. Default is linear variogram model. To utilize a custom variogram model, specify ‘custom’; you must also provide variogram_parameters and variogram_function.
