GrADS Platform Survey

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:

OpenGrADS Bundle v2.0.a7.oga.3 Released!

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

PyGrADS v1.1.2 released!

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

OpenGrADS Bundle v2.0.a5.oga.5 released!

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.

Legacy GrADS v1.10.r2 released

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

OpenGrADS Bundle 2.0.a5-oga.1 is out

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.

First Release of Win32 GrADS v2

The first OpenGrADS release of Win32 GrADS v2 is out. The packaging is similar to what we had done for v1.9.0-rc1, with both a self installing .exe and a .zip file. These can be found here:

http://sourceforge.net/project/showfiles.php?group_id=161773&package_id=290254

These are supposed to be relocatable, meaning that you can place it on a pendrive and take it around without the need for instalation. Because v2 does not support it yet, there are no
extensions included in this build. Besides a simpler instalation with a bundled Xming + a couple of CR/LF type of bug fixes, this build
should be very similar to what is being distributed by COLA.
