This import is available in DELFT-FEWS versions after 2010.02
Import NetcdfGridDataset uses NetCdf to read grid data from grib1, grib2 en NC formats.
The NetcdfGridDataset supports :
- importing ensembles,
- importing grid data from separate layers (z-dimension)
- importing grid data that are distributed over the several files, e.g. all forecasts in one file, one file per forecast, et cetera.
Starting with DELFT-FEWS versions 2011.02 NetcdfGridDataset replaces the grib1 specific import types that use JGrib decoder.
NetcdfGridDataset is in use as several import types.
This is due to the backward compatibility of the existing configurations, and due to the logical naming of the import types from the customer's point of view.
The import types below are handled by NetcdfGridDataset:
- NetcdfGridDataset: use for reading NC, reads also grib1 and grib2, however with low performance !
- grib1: use for reading grib1 format
- grib2: use for reading grib2 format
- grib2dir, grib_hirlam_flipped : old grib2 import types names, in use for backward compatibility of the configurations.
- grib, gribBasic, gribCosmo : old grib1 (Jgrib) import types name , in use for backward compatibility of the configurations.
Note:
the old JGrib based imports Grib, GribBasic, GribCosmo can be still used as import types GribOld, GribBasicOld, GribCosmoOld
