| | 56 | == Version 2.0 - December XXXXX, 2021 == |
| | 57 | |
| | 58 | Changes:[[BR]] |
| | 59 | * Added 3D-Var methods |
| | 60 | * 5 variants: 3D-Var with parameterized covariances, 3D ensemble var (ensemble covariances) and hybrid-var (combined parameterized and ensemble covariances); ensemble perturbations can be transformed using the global ESTKF or the local LESTKF |
| | 61 | * Added tutorials for 3D-Var methods (codes and slide set with explanations) |
| | 62 | * Added template files for 3D-Var methods |
| | 63 | * Added models from Lorenz (2005): model II (state with averaging), model III (two-scale); both with assimilation fully implemented |
| | 64 | * Added tutoral code showing a multivariate implementation with two model fields (/tutorial/online_2D_serialmodel_2fields). The tutorial demonstrates an efficient way to handle multiple model fields |
| | 65 | * Added possibility to reset the MPI world communicator in which PDAF operates (routine PDAF_set_comm_pdaf). This ensures compatibility with e.g. OI-servers that use processes separate from those used by the model integration. |
| | 66 | * Added possibility to let the user force that the analysis step is computed at the next call to PDAF_assimilate/PDAF_put_state (routine PDAF_force_analysis) |
| | 67 | * Added possibility to overwrite PDAF's ensemble member counting in the flexible parallelization variant and force execution of the analysis (PDAF_set_memberid) |
| | 68 | * Added routine to reset the value of the forgetting factor. Can be applied during the analysis step, e.g. to give each local analysis domain a different inflation value (PDAF_reset_forget) |
| | 69 | * Added diagnostic routine to compute the continuous ranked probability score, CRPS (PDAF_diag_crps) |
| | 70 | * Code revisions: |
| | 71 | * modernized use of MPI: now we use 'USE MPI' instead of 'include mpif.h'. This solves the issue of gfortran 10, which claimed argument mismatches |
| | 72 | * modernized use of netCDF (with 'use netcdf' instead of 'include netcdf.inc'). This also resolves the issue of gfortran 10 |
| | 73 | * observation generation (GENOBS) moved to filtertype=100 |
| | 74 | * PDAF_sampleens now works without prior call to PDAF_init (removed memory counting) |
| | 75 | * removed stub PDAF library since it is not compatible with 'USE mpi'. Thus, compiling PDAF now requires a MPI library to be installed |
| | 76 | * PDAF-OMI related |
| | 77 | * Calling deallocate_obs_pdafomi is no longer required |
| | 78 | * Model bindings for MITgcm and AWI-CM revised for using PDAF-OMI |
| | 79 | * all model implementations (Lorenz models) now implemented using PDAF-OMI |
| | 80 | * Added OMI adjoint observation operators for use with 3D-Var methods |
| | 81 | * Bug corrections: |
| | 82 | * Correction of initialization of gcoords in tutorial for obs_C_pdafomi (observations with linear interpolation) |
| | 83 | * For compatibility with the Cray compiler, all .mod files of the PDAF library are copied to /include |
| | 84 | * resolved issue of gfortran-10 complaining about argument mismatch by 'USE mpi' |
