	NetCDF - Wikipedia, the free encyclopedia
		NetCDF (Network Common Data Form) is a machine-independent, self-describing, binary data format standard for exchanging scientific data.
		A commonly used set of Unix command line utilities for netCDF files is the NetCDF Operators (NCO) suite, which provide a range of commands for manipulation and analysis of netCDF files including basic record concatenating, slicing and averaging.
		NcBrowse is a generic netCDF file viewer that includes Java graphics, animations and 3D visualizations for a wide range of netCDF file conventions.

	GSP's Guide to netCDF and R
		For the statistical readership we should note that there are contributed packages for R that allow for the efficient reading and writing of netCDF files and part of the intent of this web page is to provide some simple examples to get users started.
		A netCDF file is intended to provide all the information needed to interpret the data, as well as the data itself.
		Some netCDF files contain the data for (a set of) radiosonde instruments, some represent the output of a General Circulation Model (GCM), or a set of observations taken at a weather station, for example.

	Compressed netCDF library
		I have modified the netCDF library routines that access the data to use the zlib compression library from Jean-loup Gailly and Mark Adler (available at the zlib home page) to compress blocks of the netCDF file.
		The znetcdf library reads and writes the netcdf file in blocks (generally 8k), as does the standard netcdf library, but it goes further in that it saves in memory the last several most recently used blocks.
		When the upper layers of the netcdf library ask for a particular block from the disk file, the znetcdf library checks to see if it is currently in memory, if not it finds its location on disk and reads in the data and decompresses it (if necessary).

	NetCDF FAQ
		NetCDF (network Common Data Form) is a set of interfaces for array-oriented data access and a freely-distributed collection of data access libraries for C, Fortran, C++, Java, and other languages.
		When the netCDF format was created in 1988, 4-byte fields were reserved for file offsets, specifying where the data for each variable started relative to the beginning of the file or the start of a record boundary.
		No, version 3.6 of the netCDF library detects which variant of the format is used for each file when it is opened for reading or writing, so it is not necessary to know which variant of the format is used.

	RubyNetCDF -- Ruby interface to NetCDF
		RubyNetCDF is the Ruby interface to the NetCDF library built on the NArray library, which is an efficient multi-dimensional numeric array class for Ruby.
		NetCDF (network Common Data Form) is an array-oriented data format as well as is the library to access files of the format.
		The library of NetCDF is written in C. In addition, it has interfaces for a number of languages such as Fortran(77 and 90), Java, and Perl.

	COARDS netCDF profile (Site not responding. Last check: 2007-10-20)
		1-dimensional netCDF variables whose dimension names are identical to their variable names are regarded as "coordinate variables" (axes of the underlying grid structure of other variables defined on this dimension).
		The netCDF data type of the missing_value attribute should match the netCDF data type of the data variable that it describes.
		If it is necessary to create a netCDF file with more than 4 dimensions it is recommended that the additional dimension(s) be added "to the left" of the space and time dimensions as represented in CDL.

	Software - 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.
		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.
		Only upto 2 GB of data can be contained in a single netCDF dataset because 32-bit offsets are currently used for storing positions within the file.

	GDT netCDF conventions for climate data, version 1.3
		Case is significant in netCDF names, but it is recommended that names should not be distinguished purely by case i.e.
		The netCDF variables which contain the physical data are referred to as ``data variables'', also referred to as ``primary variables'' by Unidata.
		A coordinate variable whose dimension name is identical to its own name is referred to as a ``main coordinate variable'' in this standard, when it is necessary to distinguish it from other types of coordinate variable (sections 17, 18, 19 and 20).

		MEXNC is a mex-file interface to NetCDF files for MATLAB, and has roughly a one-to-one equivalence with the C API for NetCDF.
		It currently compiles with NetCDF library versions 3 and higher, and if it is built with 3.6.0 or higher, you may get the benefit of Large File Support if your OS supports it.
		You should be very clear on the fact that the NetCDF toolbox is currently in a bug-fixes-only state of development, and I won't be supporting it at all once NetCDF 4 is released.

	Network Common Data Form (netCDF)
		The attributes and structure for a netCDF file may be defined using the CDL, and subsequently its values may be stored via the C or Fortran interfaces.
		The netCDF distribution includes utilities ncdump and ncgen for converting netCDF files to an ASCII human-readable form (CDL) and for converting the ASCII form to a binary netCDF file or, alternatively, to a C or FORTRAN program for generating the netCDF file.
		NetCDF files may be conveyed to users by any means, including FTP, which preserves the binary structure of the file.

	EPIC - Documentation - EPIC netCDF General Conventions
		The purpose of these netCDF Conventions is to promote sharing of oceanographic observed or in-situ data and software based on the netCDF data format.
		Many longitude representations are possible, however, for compatability with the netCDF calculator function of PPLUS V1.2c (and earlier versions), use of the the West longitude convention is required.
		Although the idea of a numeric code identifying the variable may seem at first unnecessary for netCDF files, there are several advantages to having a dependable variable identifier associated with the variables in the file.

	CSM: Why netCDF? (Site not responding. Last check: 2007-10-20)
		By July of 1995 it was determined that netCDF would meet the criteria established by the working group, and would optimally meet the needs of potential users in the expected CSM community.
		NCL can access netCDF files, which is only one of many reasons it was chosen as the CSM processor (see Rationale for a Climate System Model Processor and Climate System Model (CSM) Output Processor).
		It was decided that unless netCDF failed miserably in one of the evaluation criteria, it should be the accepted CSM standard data format.

	Reading netCDF files
		These tools allow the netCDF files to be read quickly and easily and to be manipulated by many common analysis packages in addition to traditional languages such as Fortran and C/C++ and Java.
		Because netCDF format is now used for most of the different data products on the WOCE Global Data V2.0, the skills required to read one data set are the same as those needed to read all the others data sets.
		Because the netCDF files are self-describing, the attributes of each variable (such as units) and name are defined in the data set (along with other information such as the source, creation date, investigator, position, etc.).

		This document is written from a netCDF perspective and so is intended for those who have experience in netCDF.
		Since some of the functions are from the netCDF interface classes, others are from vanilla Numeric Python, and the rest are generic Python it will you to understand the basics of Python and Numeric Python before you use the Python netCDF interface.
		NetCDF defines the sizes of all variables in terms of dimensions, so before any variables can be created the dimensions they use must be created first.
