# 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 interfaces for applications and data. Separate software
|
|
distributions available from Unidata provide Java, Fortran, and C++
|
|
interfaces. They have 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. For information about a variety of analysis and display
|
|
packages that have been developed to analyze and display data in
|
|
netCDF form, see
