Expanded NetCDF Support
Use Cases
Files that use the NETCDF4_CLASSIC model
These will open and work without error.
Although the files use only data model features found in the netCDF 3 data model/API, using the netCDF 4 API will enable chunking and internal compression if the files in question were written that way.
To be safe, the software that writes the files should use the NETCDF4_CLASSIC when it makes/modifies the file(s).
Files that use some new features
Files that use all new features
These will fail with an error message indicating they are not supported along with the specific feature that caused the failure.
Unsupported NetCDF4 model/API features are:
- User defined types
- Int64 and Unsigned Int64 External Data Types
