pyPDAF.PDAF.omi_obs_op_adj_gridavg

pyPDAF.PDAF.omi_obs_op_adj_gridavg()

The adjoint observation operator of pyPDAF.PDAF.omi_obs_op_gridavg().

Parameters:

• i_obs (int) – index of observations

• nrows (int) – Number of values to be averaged

• state_p (ndarray[tuple[dim_p], np.float64]) –

  PE-local model state (dim_p)

  The array dimension dim_p is dimension of model state.

• obs_f_all (ndarray[tuple[nobs_f_all], np.float64]) –

  Full observed state for all observation types (nobs_f_all)

  The array dimension nobs_f_all is dimension of the observation.

Returns:

state_p – PE-local model state (dim_p)

The array dimension dim_p is dimension of model state

Return type:

ndarray[tuple[dim_p], np.float64]
