PDAF_OMI_Overview
v46 v47 128 128 129 129 The current version of PDAFOMI has a few limitations 130  OMI currently only supports diagonal observation error covariance matrices (though, the observation variances can vary).130  PDAF V2.3 added support for nondiagonal observation error covariance matrices **R** while older versions only supported diagonal observation error covariance matrices (though, the observation variances can vary). Using nondiagonal **R**matrices, requires a usersupplied code for operations relating to **R** (see the documentation on the implemenetation for [wiki:OMI_nondiagonal_observation_error_covariance_matrices using nondiagonal Rmatrices with OMI]) 131 131  OMI currently only includes observation operators with linear interpolation. 132 132  We have not tested interoperability with other programming languages. Generally Fortran derived data types and C structs should be compatible. Obviously, taking the Fortran routines and calling C functions to perform the actual initializations will work.
