A new project proposed by Charlie Zender (UC Irvine, PI) and Phil
Papadopoulos (UC San Diego, Co-PI), "SEI(GEO): Scientific Data
Operators Optimized for Distributed Interactive and Batch Analysis of
Tera-Scale Geophysical Data" <http://nco.sf.net#prp_sei> was funded by NSF's highly
competitive Science and Engineering Informatics program. The goal is
to develop a suite of Scientific Data Operators (SDO) for interactive
and scripted manipulation of (locally and) widely distributed
repositories of netCDF- and HDF5-formatted geophysical data. The
"grid-enabled" SDO will accelerate distributed, network-transparent,
analysis of ensemble tera-scale datasets stored at local and remote
locations.

several users noticed in the C++ interface. It is available from
ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-beta.tar.Z.
As usual, please report problems to support@unidata.ucar.edu.
2003-08-08
The
latest release, version 3.5.1-beta12, fixes what may have been a
significant performance problem. The problem was first noticed on
NEC SX6 platforms, but it is not platform-specific. It causes
extra I/O as
if unnecessary nc_sync() calls were being made. Data would be
read and written correctly, but buffers would be flushed
unnecessarily. The problem was first introduced in version 3.5.0, but
it became significantly worse in 3.5.1-beta10 as the result of another
change.
If you have installed version 3.5.1-beta10, or if netCDF I/O seems to
be a bottleneck in your application, you might want to try the new
beta release:
ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-beta.tar.Z.
As usual, please report problems to support@unidata.ucar.edu.
2003-07-22
A group of researchers at Northwestern University and Argonne National
Laboratory (Jianwei Li, Wei-keng Liao, Alok Choudhary, Robert Ross, Rajeev
Thakur, William Gropp, and Rob Latham) have designed and implemented a new
parallel interface for writing and reading netCDF data, tailored for use on
high performance platforms with parallel I/O. The implementation builds on
the MPI-IO interface, providing portability to most platforms in use and
allowing users to leverage the many optimizations built into MPI-IO
implementations. Testing so far has been on Linux platforms with ROMIO and
IBM SP machines using IBM's MPI.
Documentation and code for Parallel-NetCDF (pnetcdf) is now available for
testing.
Although a few interfaces are not implemented yet, the current implementation
is complete enough to provide significant I/O performance improvements on
parallel platforms, as described in a technical report. Users are invited to test Parallel-NetCDF
in their applications.
2003-07-01
A new beta release (3.5.1-beta11) of netCDF 3.5.1 fixes a
performance problem discovered by Gottfried Necker that had been
inadvertently introduced in the previous 3.5.1-beta10 release.
The symptom was that too much system time was used on some platforms (the
Fujitsu VPP, for example), from many extraneous calls to the internal
px_pgin() and px_pgout() library functions during I/O. The new beta
release is available from
ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-beta.tar.Z
2003-06-06

A draft of NcML, a new XML representation for netCDF data, is available at
http://www.scd.ucar.edu/vets/luca/netcdf.
Like CDL, NcML provides a human-readable and machine-parsable specification
for the structure of netCDF data, but eventually it may also be used for:
- cataloging data holdings resulting from metadata harvesting
- aggregation of data from multiple local or remote datasets
- changing or augmenting metadata in existing netCDF datasets
- support for alternate views of data (renaming components, subsetting data,
changing structure)
- declaring derived data
Please send comments and suggestions about NcML to, ncml@unidata.ucar.edu.

Patrick Jöckel of the Max Planck Institute for Chemistry has developed and
made available two new tools, ncregrid and ncdx.
ncregrid is a tool (written in FORTRAN-90) for data transfer of gridded 2-
and 3-dimensional (spatial) geophysical/geochemical scalar fields between grids
of different resolutions. The algorithm handles data on rectangular latitude/longitude
grids (not necessarily evenly spaced) and vertical pressure hybrid grids of
arbitrary resolution. The input/output data format is netCDF. ncregrid is freely
available without any warranty under the GNU public license (GPL). ncregrid
can be used as a "stand-alone" program, and/or linked as an interface to a model,
in order to re-grid automatically the input from an arbitrary grid space onto
the required grid resolution.
ncdx is a tool (also written in FORTRAN-90) that scans a netCDF file and makes
it OpenDX compliant.
ncdx is also freely available without any warranty under the GPL.
2001-12-26
Ruby is an interpreted, object-oriented
scripting language. Takeshi Horinouchi and colleagues at the Radio Science Center
for Space and Atmosphere (RASC) of Kyoto University have developed a netCDF interface
for Ruby. This interface is intended to cover all the functionality of the
C library for netCDF. Also available are combination functions such as iterators
(which offer abstract ways to scan files and variables). Numeric arrays are
handled by the "NArray" multi-dimensional array class, which is becoming the
de facto standard multi-dimensional array for Ruby.
2001-06-15
The R Project for Statistical Computing has developed R, a freely-available language and environment

NetCDF 3.5.0 is now available
in compressed tar form or
in ZIP form. No major changes to the source code have occurred since the
netCDF 3.5 beta8 release, but there have been numerous changes to the build
scripts and to the INSTALL documentation to simplify
and correct the documentation for installation on various platforms.
This release fully integrates the new Fortran 90 interface into the installation,
fixes bugs, and adds some minor enhancements. The format of netCDF files remains
the same as in previous versions, so backward compatibility is guaranteed. For
more information on the changes, see the RELEASE_NOTES.
2001-02-06
A beta release of netCDF Java (version
2) is now available.
The netCDF Java Library (Version 2) is a Java interface to netCDF files. It
is built on the MultiArray (version 2) package, which is a stand-alone Java
package for multidimensional arrays of primitive types. Also included in this
library is an experimental netCDF interface to files that are accessed through
a DODS server. The new interface
is simpler to use than version 1, and also provides some efficiencies and functionality
not available in the version 1 interface. The version 1 interface will still
be supported for existing programs that use it, but the version 2 interface
is recommended for new developments.
2001-01-31

is built on the mmap() call available on many UNIX systems. This may speed up
netCDF data access significantly in some cases. It is available as ftp://ftp.unidata.ucar.edu/pub/netcdf/contrib/mmapio.c.
This is a "drop in" replacement for libsrc/ncio.c. To use it, move ncio.c
out of way, put this file in it's place, and recompile. This has been tested
on IRIX 6.2, SunOS 5.3, and HPUX 9.

Steve Simpson (ssimpson@ziplink.net) contributed a build of netcdf-3.3 for 32
bit Windows. Here is what he had to say:
I've built 3.3 using Visual C++ 5.0 into a Win32 DLL. Enclosed
are two zip files you can post in your ftp area. The
first zip file contains the DLL and LIB files along with a readme and a
modified netcdf.h file. The
second zip file contains all the source with the modified netcdf.h file,
the readme, and the .mak and .dsp files needed by the compiler. Both files are
in WinZip format for use by PC users.
We intend to change the netcdf.h so that modifications aren't needed in the
future.

FAN version 2.0.2 (see description below) has been installed in the netcdf contrib
ftp area as ftp://ftp.unidata.ucar.edu/pub/netcdf/contrib/fan.tar.Z
This fixes a bug causing spurious 'errors' when attribute 'valid_range'
defined. Also minor change to document "Introduction to FAN Language and
Utilities".
1996-05-20
FAN version 2.0.1 has been installed in the netCDF contributed software FTP area
as ftp://ftp.unidata.ucar.edu/pub/netcdf/contrib/fan.tar.Z
FAN provides a high-level interface to netCDF.
The most generally useful facility is provided by the following four utilities:
- nc2text prints selected data from netCDF files.
- ncmeta prints selected metadata from netCDF files.
- ncrob reads data from netCDF files, performs some process on it (e.g. calculating
mean) and then either prints the result or writes it to a netCDF file.
- text2nc reads ASCII data and copies it into netCDF files. It can also create,
modify and delete attributes.
The FTP file contains the document "Introduction to FAN Language and Utilities"
in both HTML and PostScript forms. The HTML form may be viewed as: http://www.unidata.ucar.edu/software/netcdf/fan_utils.html
What is New in Version 2? The utility ncmeta is new. There are significant
enhancements to the utility ncrob. It can now print results as well as write
them to netCDF files. A number of bugs have been fixed. Further details in section
headed "What is New in Version 2?" in the above document.
The utilities have been tested on the following platforms:
- Cray Y-MP4E/464 running UNICOS 8.0.4.
- DEC alpha running OSF1 V3.2.
- DEC risc running ULTRIX V4.5.
- DEC vax running ULTRIX V4.4.
- HP 9000/715 running HP-UX A.09.05
- IBM RS6000 running AIX 4.1.
- Intel i386 running BSD/OS 2.1.
- SGI mips IP20 running IRIX 5.3.
- SGI mips IP26 running IRIX64 Release 6.1.
- Sun sparc running SunOS 4.1.4.
- Sun sparc running SunOS 5.5.
1996-05-02
The 2.4.2 release of netCDF, a minor update to netCDF 2.4, is now available via
anonymous FTP from
ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf.tar.Z
In addition, a patch file containing the differences between release 2.4.1 and
2.4.2 is available from the same directory as
ftp://ftp.unidata.ucar.edu/pub/netcdf/diffs-2.4.1-2.4.2
and the most recent Release
Notes, describes the 2.4, 2.4.1, and 2.4.2 releases.
The 2.4.2 release contains a few minor changes:
- Ported to an Intel 386-based, BSD/OS 2.1 system (but with no FORTRAN support).
- Ported to DJGPP Version 2 for MS-DOS.
- For CRAY systems, changed XDRing of scalars to use the same functions as
XDRing of vectors. This provides a workaround for a CRAY problem where the
same value written as an attribute produced a slightly different external
representation than when written as a variable.
- Added the FORTRAN interfaces macro file `linux.m4' to the distribution.
- Liberalized conditions on use and distribution of the netCDF software by
changing a sentence in the software copyright notice and in netcdf.h from
a requirement to a request.
- Fixed an ncgen bug in generating the proper value for a scalar character
variable initialized from a string in a CDL file.
1996-04-30
The netCDF FAQ has been updated
with the addition of an answer to the question: What is the best way to handle time
using netCDF?
1996-04-15
Although we don't develop or support a Windows 95 version of netCDF, Toshinobu
Hondo has contributed a port for Windows 95 compiled by Microsoft Visual C++ 4.0.
The diffs and a binary distribution are available from ftp://ftp.unidata.ucar.edu/pub/netcdf/win32/
1996-04-11
The gennet.f program for generating a Fortran program to read an arbitrary netCDF
file, contributed by Barry Schwartz of NOAA/FSL, has been updated. It's described
in the catalog and included in the directory of user-contributed
netCDF software.
The generated program now recognizes when variable IDs have changed, warns
the user when gennet should be rerun to regenerate code, permits specification
of the input file name, and adds a call to NCCLOS.
1996-04-02
Conditions on use and distribution
of the netCDF software were liberalized by changing a sentence in the software
copyright notice from
Further, the user agrees to credit UCAR/Unidata in any publications
that result from the use of this software or in any product that includes this
software.
to
Further, UCAR requests that the user credit UCAR/Unidata in any publications
that result from the use of this software or in any product that includes this
software.
Thanks to Richard Stallman, founder of the GNU project, for pointing out that
the old terms could create unnecessary problems for users and for suggesting the
change.
1996-03-19
The 2.4.1 release of netCDF, a minor update to netCDF 2.4, is now available via
anonymous FTP from
ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf.tar.Z
In addition, a patch file containing the differences between release 2.4 and 2.4.1
is available from the same directory as
ftp://ftp.unidata.ucar.edu/pub/netcdf/diffs-2.4-2.4.1
The 2.4.1 release contains fixes for a portability problem in the previous 2.4
release, an ncgen bug, and a few documentation updates:
- Slightly modified VAX OpenVMS build mechanism: made `makevms.com' command
procedures VAX-C specific in order to better specify the build environment
and avoid incompatibilities.
- Slightly modified ncdump/ncdump.c: expanded use of isprint() into two statements
to avoid problems under Alpha OpenVMS where that function is actually a complicated
macro.
- Fixed ncgen bug in filling one-dimensional string variables when specified
with multiple values that should be concatenated, eliminating spurious "too
many values for this variable" message.
- In User's Guide, added links to C++ and netCDFPerl interface documentation.
See the Release Notes
for a description of what's new in the 2.4 release.
1996-03-04
The Frequently Asked Questions about
netCDF document has just been updated to state that the OpenVMS-6.2 platform
on which the latest release of netCDF was tested was a Digital MicroVAX, not a
Digital Alpha.
Unidata is looking for a volunteer site in Europe to mirror the netCDF software
distribution. [A site volunteered, see mirror sites.]
1996-03-01
Binary versions of the netCDF 2.4 release are now available for a few platforms:
The source release (from which the above binaries were built) is available from
ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf.tar.Z.
The NetCDF 2.4 User's Guide is available separately as a PostScript file, a
set of info files,
or a web document.
1996-02-28
The 2.4 release of netCDF is now available. See the Release Notes for a description
of what's new in the release. The freely
available source can be obtained by anonymous FTP from: ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf.tar.Z.
This release provides a new version of the netCDF software that incorporates support
for new platforms and updated versions of previously-supported platforms, provides
new optimizations, improves the documentation, incorporates fixes for reported
bugs, and includes other miscellaneous improvements. Version 2.4 is intended to
be a stable release incorporating bug fixes and improvements that do not involve
significant additions to the netCDF data model or interfaces.
1996-02-16
A new version of the NetCDF User's Guide for the 2.4 release is now available
in several forms:
- HTML
- as a set of HTML documents for viewing with a web browser.
- PostScript
- as a compressed PostScript file. When uncompressed, this is suitable for
printing or viewing with a PostScript viewer. (In the PostScript file, the
Table of Contents is printed last, so please reorder before duplicating.)
- Info files
- as a compressed tar file of Info files, suitable for viewing with an Info
documentation browsing system such as GNU info.
Changes to the new User's Guide include the following:
- a new appendix that formally specifies the netCDF format, independent of
its implementation;
- a new section on limitations of the netCDF data model and implementation;
- a new section on compiling and linking with the netCDF library;
- a new section on UNICOS optimization;
- a new section discussing the correspondence between CDL, netCDF, FORTRAN,
and C data types;
- clarification of, and some changes to, recommended standard attribute conventions;
- clarification of cross-section access, strided access, and mapped access
to arrays;
- better embedding of URLs, so the derived HTML form of the User's Guide
has working links to external documents and references; and
- a more useful Index.
We expect to release version 2.4 of the netCDF software next week. It is currently
available only in a beta test version, from netcdf-beta.tar.Z
1996-01-10
We have added nctopnm, a contributed program from Bear Giles of NOAA/FSL, to the
catalog and directory of user-contributed
netCDF software. Here's a brief description:
NCTOPNM converts a NetCDF "image" field (a two-dimensional
(finite) or three-dimensional (unlimited) field of "char" or "byte"
data) into a PNM portable pixmap. It can use a pseudo-color or greyscale colormap
in the same file or a different file, add a colorbar to the lower left corner
of the image, and "burn in" a map background.
1996-01-08
The version 2.4 beta6 release of netCDF was made available via anonymous FTP from
the directory ftp://ftp.unidata.ucar.edu/pub/netcdf/.
The compressed tar file is netcdf-beta.tar.Z
(a link to the most recent beta release). This release contains fixes for:
- a bug in not recognizing the new names of variables and dimensions renamed
in define mode;
- a bug in ncdump that caused it to print the explicit fill value instead
of "_" for floating-point variables that had a negative "_FillValue"
attribute;
- a bug in using the "-f" option of ncdump for full annotations,
in which multidimensional character arrays were missing a comma delimiter;
- memory leaks in ncdump for some option combinations.
The release notes
list operating systems on which the beta release has been tested, describe what's
new since release 2.3.2pl2, and describe other problems that have been fixed.
1995-12-06
The beta5 release of netCDF 2.4 was made available via anonymous FTP from the
directory ftp://ftp.unidata.ucar.edu/pub/netcdf/.
The compressed tar file is netcdf-beta.tar.Z

directory ftp://ftp.unidata.ucar.edu/pub/netcdf/.
The compressed tar file is netcdf-beta.tar.Z
(a link to the most recent beta release). This release adds some Windows NT-specific
files inadvertently left out of the beta2 release (libsrc/winnt_io.h, util/make.com,
util/msoft.mk, util/getopt.c, ncgen/msoft32.mak), and includes minor changes necessary
for porting to IRIX64-6.1, and changes to configure to use the c89 compiler in
preference to cc on AIX platforms.
1995-10-26
We announced the availability of the first release of Harvey Davies' FAN Utilities,
a new software package for manipulating netCDF data. FAN
(File Array Notation) is an array-oriented notation for identifying data items
in files for the purpose of extraction or modification.
The three utility programs in the initial release (nc2text, text2nc, and ncrob)
can greatly decrease the need for programming with the netCDF library interfaces,
since they can be called from the Unix command line and shell scripts.
The package is available via anonymous FTP from ftp://ftp.unidata.ucar.edu/pub/netcdf/contrib/fan.tar.Z.
Questions and comments may be sent to Harvey Davies, hld@dar.csiro.au.
1995-10-19
The Software for Manipulating
or Displaying NetCDF Data document has been revised and reorganized to list
packages according to whether they are freely-available or licensed. New entries
were added for DODS, EWB, LinkWinds, PolyPaint+, and PPLUS. A few old entries
were deleted, and links that don't work were updated or deleted.
1995-10-13
The beta2 release of netCDF 2.4 was made available via anonymous FTP from the
directory ftp://ftp.unidata.ucar.edu/pub/netcdf/.
The compressed tar file is netcdf-beta.tar.Z
(a link to the most recent beta release). This release adds support for Windows
NT, including Makefiles and code contributed by Donald W. Denbo of Pacific Northwest
Laboratory (thanks Don!). Also a bug in ncattput is fixed and VMS fortran jacket
library code was regenerated.
The search form on the netCDF
home page has been revised. It now uses WAIS directly instead of going through
a gopher gateway. Also, help is now available on the syntax of query expressions.
1995-10-12
The Frequently Asked Questions
web page has been rewritten, organizing the questions so it's easier to find
a specific answer, and revising the document to include mention of the netCDF
2.4 beta release. A few new questions have also been included.
1995-10-11
A beta release of netCDF 2.4 is now available in source form via anonymous FTP
from the directory ftp://ftp.unidata.ucar.edu/pub/netcdf/.

been tested on AIX-4, HPUX-9, IRIX-5, OSF1-3, SunOS-4, SunOS-5, Ultrix-4, and
Unicos-8 platforms. It has not yet been tested on VMS, MSDOS, or Windows. The
NetCDF User's Guide in the release has not been completely updated to version
2.4 yet, and additions to the C++ interface have yet to be documented. We're
very interested in feedback from early testers of this beta release of netCDF
2.4, especially if you notice bugs that have been reported but not fixed or incompatibilities
with netCDF 2.3.
The purpose of release 2.4 of netCDF is to:
- Provide support for new platforms
- Provide significant Cray optimizations
- Incorporate fixes for all reported bugs
- Improve ease of installation
- Update documentation
1995-07-07
We have added two contributed programs from Charlie Zender, ncks and ncrename,
to the catalog and directory of contributed
netCDF software.
Work on release 2.4 of netCDF continues. We hope to be able to announce a beta
release soon.
1995-06-23

1995-06-07
netCDFPerl, a netCDF
interface for the perl utility, is now available.
1995-05-18
The netCDF homepage was changed in some cosmetic ways to adapt to a more uniform
look for Unidata WWW pages.
1995-05-11
The netCDF 2.3pl2 release has been built and tested on AIX 4.1.2. It builds and
tests cleanly. The compiler problem that exists with AIX 3.2.x is no longer an
issue.
1995-05-09
A new draft document includes
a draft list of what will be in the upcoming netCDF 2.4 release. The document
also lists some possibilities for future enhancements to netCDF.
1995-04-18
The document on Known Problems with the netCDF
Distribution has been updated with a few new entries. In particular, how to
get an early test version of netCDF for IRIX64 platforms and a workaround for
a problem with building the Fortran netCDF interface on some Cray platforms are
now included.
1995-02-24
There's a new document
explaining netCDF mailing lists. These are now handled by the majordomo list handler.
References to the new document have been added to the FAQ and netCDF home page.
1995-02-06
We added some additional comments to the descriptive text for patches 3 and 4
to the netCDF distribution (all available fromftp://ftp.unidata.ucar.edu/pub/netcdf/)
that fix some bugs found in the experimental netCDF C++ interface, pointing out
that after applying patch 3 it is necessary to build the netCDF library from scratch,
including rerunning the `configure' script.
1995-02-03
A new version of Barry Schwartz's program to generate a Fortran program to
read a netCDF file is now available in the directory of user-contributed netCDF
software maintained at the Unidata Program Center. It opens a specified netCDF
file and generates the necessary Fortran code to declare the corresponding Fortran
dimensions and variables and read all the data into the Fortran variables.
1995-02-02
A new version of David Pierce's Ncview visual browser for netCDF data is now
available in the directory of user-contributed netCDF
software maintained at the Unidata Program Center. Ncview is an X11 application
that displays a 2-dimensional color representation of single precision floating
point data in a netCDF file. You can animate the data in time (making simple movies),
flip or enlarge the picture, scan through various axes, change colormaps, etc.
The new version has many minor bug fixes, portability enhancements, ability to
read non-floating point data, and other improvements.
1995-01-31
A new patch is now available from ftp://ftp.unidata.ucar.edu/pub/netcdf/2.3.2-patch4
that fixes some bugs found in the netCDF C++ interface. It updates the netCDF
software to version 2.3.2pl4. Before applying this patch, you should first apply
patch 3, available from ftp://ftp.unidata.ucar.edu/pub/netcdf/2.3.2-patch3.
The beginning of the patch file includes brief descriptions of the bug fixes contained
in patch4.
1995-01-20
We have made available a new Web document listing known problems (and workarounds,
where available) with the current netCDF distribution. You can get to the new
document from the netCDF homepage or directly using the URL http://www.unidata.ucar.edu/software/netcdf/known_problems.html.
1994-12-16
There's a new file, watcom.zip, in the ftp://ftp.unidata.ucar.edu/pub/netcdf/contrib/
directory of user-contributed software. Mike Perryman
contributed this collection of makefiles for building netCDF on DOS or OS/2 platforms
using the WATCOM compilers. These files could be used to drive other DOS or OS/2
compilers with minimal modification since the compiler, linker and librarian specifications
are contained only in the base makefile. This is packaged as a PKZIP file containing
makefiles named WATCOM.MK for the base netCDF directory and subdirectories.
1994-11-23
Frank Dzaak (dzaak@fm.bs.dlr.de) contributed his fixes for building netCDF on
