A netCDF dataset contains dimensions , variables , and attributes , which all have both a name and an ID number by which they are identified. These components can be used together to capture the meaning of data and relations among data fields in an array-oriented dataset. The netCDF library allows simultaneous access to multiple netCDF datasets which are identified by dataset ID numbers, in addition to ordinary file names. This provides a fast and compact storage method.
Case is significant in netCDF names.
We will use a small netCDF example to illustrate the concepts of the netCDF data model. This includes dimensions, variables, and attributes. The netCDF system includes utilities for producing human-oriented CDL text files from binary netCDF datasets and vice versa. The CDL notation is simple and largely self-explanatory. It will be explained more fully as we describe the components of a netCDF dataset.
