6 Summary: python/numpy interface to netCDF library (versions 3 and 4)
7 License: OSI Approved
8 Description: netCDF version 4 has many features not found in earlier versions of the library
9 and is implemented on
10 top of HDF5. This module can read and write files in both the new netCDF 4 and
11 the old netCDF 3
12 format, and can create files that are readable by HDF5 clients. The API modelled
13 after
14 Scientific.IO.NetCDF, and should be familiar to users of that module.
15
16 Most new features of netCDF 4 are implemented, such as multiple unlimited
17 dimensions, groups and zlib data compression. All the new numeric data types
18 (such as 64 bit and unsigned integer types) are implemented. Compound,
19 variable length (vlen), and enumerated (enum) data types are supported, but
20 the opaque type is not. Mixtures of compound, vlen and/or enum data types are not supported.

5853 single file. Variables in the list of files that share the same
5854 dimension (specified with the keyword <code>aggdim</code>) are aggregated. If
5855 <code>aggdim</code> is not specified, the unlimited is aggregated. Currently,
5856 <code>aggdim</code> must be the leftmost (slowest varying) dimension of each
5857 of the variables to be aggregated.</p>
5858 <p><strong><code>files</code></strong>: either a sequence of netCDF files or a string with a
5859 wildcard (converted to a sorted list of files using glob) If
5860 the <code>master_file</code> kwarg is not specified, the first file
5861 in the list will become the "master" file, defining all the
5862 variables with an aggregation dimension which may span
5863 subsequent files. Attribute access returns attributes only from "master"
5864 file. The files are always opened in read-only mode.</p>
5865 <p><strong><code>check</code></strong>: True if you want to do consistency checking to ensure the
5866 correct variables structure for all of the netcdf files. Checking makes
5867 the initialization of the MFDataset instance much slower. Default is
5868 False.</p>
5869 <p><strong><code>aggdim</code></strong>: The name of the dimension to aggregate over (must
5870 be the leftmost dimension of each of the variables to be aggregated).
5871 If None (default), aggregate over the unlimited dimension.</p>
5872 <p><strong><code>exclude</code></strong>: A list of variable names to exclude from aggregation.
5873 Default is an empty list.</p>
5874 <p><strong><code>master_file</code></strong>: file to use as "master file", defining all the
5875 variables with an aggregation dimension and all global attributes.</p></div>
