3.2 NetCDF Features
Several characteristics make netCDF useful for storing and accessing
- Self-Describing: A netCDF file may include metadata as
well as data: names of variables, data locations in
time and space, units of measure, and other useful information.
Data written on one platform can be read on other platforms.
A small subset of a large dataset may be accessed efficiently,
without first reading through all the preceding data.
Data may be efficiently appended to a
netCDF file without copying the dataset or redefining its
The netCDF library provides client access to structured data on remote
servers through OPeNDAP protocols.
Adding new dimensions, variables, or attributes to netCDF files does
not require changes to existing programs that read the files.
One writer and multiple readers may simultaneously access the
same netCDF file. With Parallel netCDF, multiple writers may
efficiently and concurrently write into the same netCDF file.
Access to all earlier forms of netCDF data will be supported by
current and future versions of the software.
