Unidata NetCDF
|
|
|
|
The Unidata network Common Data Form (netCDF) is an interface for
|
|
scientific data access and a freely-distributed software library that
|
|
provides an implementation of the interface. The netCDF library also
|
|
defines a machine-independent format for representing scientific data.
|
|
Together, the interface, library, and format support the creation,
|
|
access, and sharing of scientific data. The current netCDF software
|
|
provides C, Fortran-77, Fortran-90, and C++ interfaces for
|
|
applications and data. It has been tested on various common
|
|
platforms.
|
|
|
|
NetCDF files are self-describing, network-transparent, directly
|
|
accessible, and extendible. `Self-describing' means that a netCDF file
|
|
includes information about the data it contains. `Network-transparent'
|
|
means that a netCDF file is represented in a form that can be accessed
|
|
by computers with different ways of storing integers, characters, and
|
|
floating-point numbers. `Direct-access' means that a small subset of a
|
|
large dataset may be accessed efficiently, without first reading through
|
|
all the preceding data. `Extendible' means that data can be appended to
|
|
a netCDF dataset without copying it or redefining its structure.
|
|
|
|
NetCDF is useful for supporting access to diverse kinds of scientific
|
|
data in heterogeneous networking environments and for writing
|
|
application software that does not depend on application-specific
|
|
formats. A variety of analysis and display packages have been developed
|
|
to analyze and display data in netCDF form.
|

You can obtain a copy of the latest released version of netCDF software
|
|
using a WWW browser or anonymous FTP from

ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf.tar.Z
|
|
|
|
Included in this distribution are: the C source for the netCDF data
|
|
access library, sources for the FORTRAN and C++ interfaces,
|
|
documentation for the netCDF library and utilities in the form of a
|
|
netCDF User's Guide, source for the netCDF utilities ncdump and ncgen,
|
|
and test programs to verify the correct implementation of the netCDF
|
|
library.

To install this package, please see the file INSTALL in the
|
|
distribution, or the (possibly more up-to-date) document:
|
|
|
|
http://www.unidata.ucar.edu/software/netcdf/docs/netcdf-install/
|
|
|
|
The netCDF-3 C and FORTRAN-77 interfaces are documented in man(1)
|
|
pages in the distribution in files netcdf.3 and netcdf.3f,
|
|
respectively, or at
|
|
|
|
http://www.unidata.ucar.edu/software/netcdf/docs
|
|
|
|
User's Guides for C, FORTRAN, and FORTRAN-90 are also available in
|
|
several forms from the same location.
|
|
|
|
A mailing list, netcdfgroup@unidata.ucar.edu, exists for discussion of
|
|
the netCDF interface and announcements about netCDF bugs, fixes, and
|
|
enhancements. For information about how to subscribe, see the URL

An archive of past postings to the netcdfgroup mailing list is available
|
|
for searching from the netCDF home page.
