v5 v6 27 27 * For the local filters (LESTKF, LETKF, LSEIK) `dim_obs_p` is the observation dimension for the `full` observations. 28 28 * The array `Uinv` is only needed for SEEK filter. Also one needs its values for the ESTKF, ETKF, and SEIK filter to compute the analysis error covariance matrix when these filters used with a fixedcovariance matrix (subtype=3). In all other cases the ensemble array `ens_p` contains all required information. 29 * The interface has a difference for ETKF and ESTKF: For the ETKF, the array `Uinv` has size `dim_ens` x `dim_ens`. In contrast it has size `dim_ens1` x `dim_ens1` for the ESTKF. (For most cases, this will be irrelevant, because most usually the ensemble array `ens_p` is used for computations, rather than `Uinv`. Only for the SEIK filter with fixed covariance matrix, `Uinv` is required to compute the estimate analysis error. The fixed covariance matrix mode is not available for the ETKF or ESTKF.) 30 * For the local filters (LESTKF, LETKF, LSEIK) the matrix `Uinv` does not contain useful information, because its values are from the last processed local analysis domain only. 29 31 30 32 Hints:
