The Windows binaries for OpenGrADS 2.2.1 have been refreshed to address an issue with the BACKSPACE key. All are encouraged to re-download. The other OS builds are not affected, this issue is specific of Windows.

We have just released the OpenGrADS Bundle version 2.2.1.oga.1 for Windows, macOS and Linux. This is a major release after a 2 year hiatus. This release fixes an earlier limitation that prevented access to https:// OPeNDAP sites and bring several new features such as dynamically linked graphical backends.

GrADS/VM is an EXPERIMENTAL version of GrADS that runs entirely under the Java Virtual Machine. GrADS/VM is based on the same C source code used in the other versions of GrADS and uses NestedVM for binary translation into Java Bytecode. we just upload the experimental GrADS/VM builds for versions 2.0.1 & 2.0.2 to sf.net. These can be found under then"Java" subdirectory of the grads2 package, e.g., https://sourceforge.net/projects/opengrads/files/grads2/2.0.2.oga.2/Java

JyGrADS is a repackaging of the Python Interface to GrADS (PyGrADS) for use under Java, and through Java, for interfacing to any Java-friendly application such as MATLAB. At the core of JyGrADS is Jython, an implementation of the high-level, dynamic, object-oriented language Python written in 100% Pure Java, and seamlessly integrated with the Java platform. For additional information consult http://opengrads.org/wiki/index.php?title=JyGrADS:_Java_and_Matlab_interface_to_GrADS_through_Jython.

We have just releasd the OpenGrADS Bundle version 2.0.2.oga.2 for Windows, Mac OS X and Linux. This is a minor maintenance release which fixes a bug that prevented the proper reading of NetCDF files with levels having units as "hPa". It should now be able to read files from the MERRA reanalysis and NASA's GEOS-5 output. It also updates the OpenGrADS extensions to the same version as in the OpenGrADS v2.1.a2.oga.1 release.

A new release of supplemental libraries needed for building GrADS and ancillary packages (the so calleed "supplibs") is now available. Version 2.3.1 includes all you need for building GrADS 2.1.a2 and is available for Mac OS X, Linux, and Windows.

This OpenGrADS version is based on COLA's 2.1.a2 release with updates
in the OpenGrADS extensions. In particular we include the new "path"
extension with many convenient commands (and GrADS script functions)
for pathname maniputation and match and search & replace functionality
based on regular expressions. Enjoy!

We have release a minor, maintenance release of PyGrADS, Version 1.1.9. Consult ChangeLog for details.

We have just uploaded the Windows build for the OpenGrADS Bundle Version 2.0.2.oga.1. Enjoy!

After a very long hiatus, we have just released the OpenGrADS Bundle version 2.0.2.oga.1 for Mac OS X and Linux; the Windows version will be released soon. This OpenGrADS version is based on COLA's 2.0.2 release with a couple of additions to the OpenGrADS extensions (a spherical harmonic based Poisson solver and a new satellite orbital masking based on TLE files.) This is meant to be a stable release. Enjoy!

Release 1.1.8 of PyGrADS is now available. It fixes an issue with gacm with newer versions of matplotlib, and some annoying bugs in galab. See the ChangeLog for details. Gaya, the interface to Mayavi is still in preview mode --- your feedback is appreciated.

A new release of supplemental libraries needed for building GrADS and ancillary packages (the so calleed "supplibs") is now available. Version 2.2.1 includes all you need for building GrADS 2.0.1 and wgrib 0.1.9.4 and is available for Mac OS X, Linux, FreeBSD and Windows.

After a long time without updating the GRIB-2 swiss arm knife utility (wgrib2) we have just release binaries for the latest wgrib2 0.1.9.4. Enjoy!

We have just released the OpenGrADS Bundle version 2.0.1.oga.1 for Mac OS X. Linux and FreeBSD; the Windows version will be released soon. This OpenGrADS version is based on COLA's 2.0.1 release with very minor updates in the OpenGrADS extensions. This is meant to be a stable release.

We have just released the OpenGrADS Bundle version 2.0.a9.oga.1 for Windows, Mac OS X and Linux; the FreeBSD version will be released soon. This OpenGrADS version is based on COLA's 2.0.a9 release with very minor updates in the OpenGrADS extensions. This version introduces a new GIS interface for creating shapefiles with contours
(from gridded data) or points (from station or gridded data sets). Consult the ChangeLog for additional information on new features.

As we try to prioritize development at the OpenGrADS project, it becomes important for us to understand the particular platforms and operating systems folks are running GrADS on. Therefore we have designed a very quick survey to collect this information. We'd be very appreciative if users could spare 5 minutes of their time and complete this short survey:

This version is based on COLA's 2.0.a7 release which includes a new interface for the native HDF-5 format, options for templating on Julian Day and time axis, new funtion eloop, in addition to some bug fixes. See the ChangeLog for details.

This OpenGrADS release adds support for LATS, a feature of GrADS v1.x which has been dropped from COLA's GrADS v2.0 codebase. LATS is now implemented as an OpenGrADS extension giving users the ability to write NetCDF-3, NetCDF-4/HDF-5 (with and without compression), HDF-4 and GRIB-1 from a single GrADS executable. This release also adds the extension ORB which allows you to mask gridded variables according to several satellite orbits. See the included "Documentation.html" for an in-depth description of these new extensions.... read more

This is pretty much a bug fix release of PyGrADS. It includes a better handling of the e-dimension under GrADS v2.0, returning a single e-dimension under GrADS v1.x. It also includes the ga.query("time") method which returns both GrADS and Unix time representations. The default GrADS binary is now "grads" instead of
"gradshdf". Recall that under GrADS v2.0.a5.oga.5 and v1.10.r2.oga "grads" includes support for most data formats, including OpenGrADS... read more

This is primarily a bug fix release: fixed the ipc_load() bug -- now we should have a fully functional pygrads v1.12 with GrADS v2. In addition, the "printim -b" bug has been fixed, and Mike Fiorino's extensions have been updated. We have also revised the implementation of the patch that allows up to 256 colors. See the ChangeLog for additional details.

Binaries are available for Windows, Mac OS X, Linux and FreeBSD.

A maintenance version of GrADS v1.10.r2 has been released. This version includes bug fixes on top of GrADS v1.9.0-rc1, and some features that had been contributed by NRL earlier on. For this reason, we have bumped the version number from 1.9 to 1.10. For ease of maintenance, we have adopted the same build mechanism and extension API of v2.0, including the OpenGrADS Bundle concept. See the ChangeLog for a detailed description of what is included in this version. ... read more

Since the main development has now shifted to GrADS v2 we have replaced the GrADS v1.x sources on the TRUNK with the sources previously on GRADS2_DEV_BRANCH.

1) If you would like to to checkout the bleeding edge GrADS v2 sources (not recommended, you must know what you are doing):

% gacvs co -P Grads

2) If you would like to to checkout the bleeding edge GrADS v1.10 sources (not recommended, you must know what you are doing):... read more

A small revision of the top GNUmakefile now makes it possible to build hdf4-nc/, another build of HDF-4 with the NetCDF enable. This feature is neded for building the upcoming GrADS v1.10. No need to upgrade unless you intend to build GrADS v1.10.

This is a maintenance release. Besides small bug fixes, it raises the maximum number of colors from 100 to 256.

The OpenGrADS Bundle is a new way of packaging GrADS builds that is somewhat inspired on the Win32
Superpacks. The idea is to have a single package that require no (minimum?) configuration and that is easily relocatable. This version is based on COLA's 2.0.a5 release which includes support for GeoTIFF and KML, as well as bug fixes. In addition, several OpenGrADS specific enhancements have been introduced such as a single binary that can handle all supported formats: NetCDF-3 (classic NetCDF), NetCDF-4/HDF-5, HDF-4, GRIB-1/2 and grads binaries. A preview release of the OpenGrADS extensions with gxyat, re, fish, shape and many others is also included.

The first release in almost a year of NCEP's "Swiss Army Knife" for manipulating GRIB-2 files. Lots of new features and bug fixes.
