    26 || The PDAF3 interface introduced by PDAF3 also provides support for non-diagonal R matrices. For details, see the [wiki:nondiagonal_observation_error_covariance_matrices_PDAF3 page on PDAF3 assimialtion interface for non-diagonal R matrices] ||

    2828The default mode of PDAF-OMI is to use a diagonal observation error covariance matrix **R** and specifying the observation error variances, i.e. the diagonalof **R** only. This is in line with the common choice in data assimilation to assume that observation errors are uncorrelated.
