pyPDAF.PDAF.omi_gather_obs

pyPDAF.PDAF.omi_gather_obs()

This function is typically called in the user-supplied function py__init_dim_obs_pdaf. This function returns the full observation dimensioin from process-local observations. It also sets the observation vector, its coordinates, and the inverse of the observation variance. This function furtuer sets the localisation radius in OMI.

Parameters:

• i_obs (int) – index of observations

• obs_p (ndarray[tuple[dim_obs_p], np.float64]) –

  pe-local observation vector

  The array dimension dim_obs_p is State dimension

• ivar_obs_p (ndarray[tuple[dim_obs_p], np.float64]) –

  pe-local inverse observation error variance

  The array dimension dim_obs_p is State dimension

• ocoord_p (ndarray[tuple[thisobs(i_obs)%ncoord, dim_obs_p], np.float64]) –

  pe-local observation coordinates

  The 1st-th dimension dim_obs_p is State dimension

• cradius (float) – localization radius

Returns:

dim_obs – Full number of observations

Return type:

int
