GrADS/VM: GrADS under the Java Virtual Machine

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

Java and Matlab interface to GrADS through Jython Released

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.

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 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.
