pyPDAF.PDAFomi.set_localize_covar_iso

pyPDAF.PDAFomi.set_localize_covar_iso(i_obs: int, dim: int, ncoords: int, coords: np.ndarray, locweight: int, cradius: float, sradius: float) → None

Initialise local observation information for isotropic covariance localisation.

This is used in stochastic EnKF/EAKF/EnSRF. This is called in user-supplied functions pyPDAF.c__init_dim_obs_pdaf().

Parameters:

• i_obs (int) – index into observation arrays

• dim (int) – State dimension

• ncoords (int) – number of coordinate directions

• coords (ndarray[np.float64, ndim=2]) – Coordinates of state vector elements Array shape: (:,:)

• locweight (int) – Localization weight type

• cradius (double) – localization radius

• sradius (double) – support radius for weight functions
