All,
I just upload to sf.net version *2.0.a7.oga.3 *of the *OpenGrADS
Bundle*. 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 (see http://opengrads.org/doc/udxt/lats/) 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. With the LATS
extension, Lats4D <http://opengrads.org/wiki/index.php?title=Lats4D> has the
same capabilities in GrADS v2.0 as it once did in GrADS v1.x.
This release also adds the extension *ORB* (see
http://opengrads.org/doc/udxt/orb/) which allows you to mask gridded
variables according to several satellite orbits.
*NOTE:* Unless you are interested in these new extensions, there is no
reason to upgrade from v2.0.a7.oga.2.
For downloading,
*Linux, Mac OS X, sources:*
http://sourceforge.net/projects/opengrads/files/grads2-windows/2.0.a7.oga.3/
*Windows:*
http://sourceforge.net/projects/opengrads/files/grads2-windows/2.0.a7.oga.3/
The NEWS file is reproduced below. Remember, these extensions should be
considered experimental. Use at your own risk.
Enjoy and let me know of any problems.

The OpenGrADS Bundle Distribution

GrADS Version 2.0.a7.oga.3
Released 29 October 2009
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 extention 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.
Several other important OpenGrADS additions are available with this version:
- grads is now built with NetCDF v4.0.1beta3 which includes support
for NetCDF-4/HDF-5 (similar to gradsnc4 in v1.9.0-rc1) and has
built in OPeNDAP support.
- gradsdap is no longer provided as its functionality is now included
in the single executable *grads*.
- this is an OpenGrADS Bundle release, a relocatable, minimum
configuration package that has all that you need to run GrADS. See
INSTALL for additonal information.
- we have introduced option -C to enable colorized text
- preview release of the OpenGrADS Extensions; the same extensions
available in GrADS v1.9.0-rc1 are now available with GrADS v2.0.
Caveat: as COLA is yet to publish the official API for User Defined
functions in GrADS v2.0 we have adopted here an API that
is based on our work vith v1.9.0-rc1. This is a very low-level
API that is *not* endorsed by COLA. As such, it is *not*
advisable
that users adopt this API to write their own extensions.
- These extensions are still being fully tested. Please report any problems
you encounter. Use them at your own risk.
- The following extensions are included: see below.
