pyPDAF.PDAFomi.set_localize_covar_noniso¶

pyPDAF.PDAFomi.set_localize_covar_noniso()¶

Initialise local observation information for non-isotropic covariance localisation.

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

Here, localisation radii differ for each spatial dimension.

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 (ndarray[np.float64, ndim=1]) – Vector of localization cut-off radii Array shape: (:)
sradius (ndarray[np.float64, ndim=1]) – Vector of support radii of localization function Array shape: (:)
