# Unidata NetCDF
[![latest packaged version(s)](https://repology.org/badge/latest-versions/netcdf.svg)](https://repology.org/project/netcdf/badges)
### About
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, Python,
and C++ interfaces. They have been tested on various common
platforms.
#### Properties
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.
#### Use
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
* [Software for Manipulating or Displaying NetCDF Data](https://www.unidata.ucar.edu/netcdf/software.html)
