NetCDF Format Versions
There are several ways to represent netCDF data.
Classic File Format
Understanding the netCDF classic format can make clear why modifying the schema of an existing netCDF file may be expensive.
Classic API Performance Tips
Avoid premature optimization: worry about performance only after you determine netCDF I/O is a bottleneck.
Using Less Space for Data
Using less disk space for your data can also reduce access time.
Using Less Time for Data Access
If netCDF access time is a bottleneck, these techniques may help.
