Opening & Editing NetCDF / NcML Files

Supported File Formats

The NetCDF Multi-Page Editor natively handles:

• .nc, .nc3, .nc4, .cdf, .netcdf: Binary NetCDF formats (NetCDF-3 Classic/64-bit, NetCDF-4/HDF5).
• .ncml: XML-based NcML 2.2 dataset definitions.
• .hdf5, .h5: Hierarchical Data Format files.

Inspecting and Editing Dataset Metadata

1. Open the dataset in the NetCDF Multi-Page Editor.
2. In the tree view, expand the Dimensions node to verify dimension lengths and unlimited status.
3. Expand the Variables node to inspect data types (e.g. float, double, short) and shape strings (e.g. time height1 y x).
4. Expand any variable to view its Attributes (units, long_name, standard_name, _FillValue, valid_min, valid_max).
5. Use the Properties View (Window > Show View > Properties) to modify attribute values or add new user-defined metadata.
6. Switch to the Source Tab to view and edit the raw NcML XML directly with syntax highlighting.
