1Unidata NetCDF Fortran Library 2======================================== 3 4Overview 5-------- 6 7 8The Unidata network Common Data Form (netCDF) is an interface for scientific data access and a set of freely-distributed software libraries that provide 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. This software package provides Fortran application interfaces for accessing netCDF data. It depends on the netCDF C library, which must be installed first. Other separate software distributions available from Unidata provide C Java, C++, and Python. They have been tested on various common platforms. 9 10NetCDF 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. 11 12NetCDF 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 13 14* http://www.unidata.ucar.edu/netcdf/software.html 15 16For more information about netCDF, see the netCDF Web page at 17 18* http://www.unidata.ucar.edu/netcdf/ 19 20The netCDF Fortran libraries contain both F77 and F90 APIs. For documentation see 21 22* https://www.unidata.ucar.edu/software/netcdf/docs-fortran/ 23 24### Code Status 25 26NetCDF-Fortran uses [Travis-CI](http://travis-ci.org) for continuous integration testing. This helps to ensure that developer changes do not break the netCDF-Fortran code base. 27 28Continuous Integration Testing Suite | Status 29---------------- | ----------- 30Travis-CI | <IMG SRC="https://travis-ci.org/Unidata/netcdf-fortran.svg?branch=master"/> 31 32 33Getting NetCDF 34-------------- 35 36You can obtain a copy of the latest released versions of netCDF software from 37 38* http://github.com/Unidata/netcdf-c 39* http://github.com/Unidata/netcdf-fortran 40* http://github.com/Unidata/netcdf-cxx4 41* http://github.com/Unidata/netcdf4-python 42 43Copyright and licensing information can be found here, as well as in the COPYRIGHT file accompanying the software 44 45* http://www.unidata.ucar.edu/software/netcdf/copyright.html 46 47To install this package, please see the document: 48 49* http://www.unidata.ucar.edu/software/netcdf/docs/building_netcdf_fortran.html 50 51Additional Documentation 52------------------------ 53 54Previous varsions of the netCDF-3 C and FORTRAN-77 interfaces are 55documented at 56 57* http://www.unidata.ucar.edu/netcdf/documentation/historic/ 58 59Mailing List 60------------ 61 62A mailing list, netcdfgroup@unidata.ucar.edu, exists for discussion of the netCDF interface and announcements about netCDF bugs, fixes, and enhancements.
