<DIV style="MARGIN: 0px"><FONT style="FONT: 12px Helvetica"
face=Helvetica size=3>Because NCEP will soon be distributing forecast
data only in GRIB2 format, we are releasing an alpha version of GrADS
2.0. We are still actively testing and debugging and documenting the
code, but it is working well for us internally at COLA, and we feel the
time is right for a public release.?/font></DIV>
<DIV><BR class=webkit-block-placeholder></DIV>
<DIV style="MIN-HEIGHT: 14px; MARGIN: 0px; FONT: 12px Helvetica">GrADS
2.0 is a significant upgrade from 1.9 in many ways:?/div>
<DIV style="MARGIN: 0px"><FONT style="FONT: 12px Helvetica"
face=Helvetica size=3>-- it has 'dtype grib2' and a new utility
'grib2scan'?/font></DIV>
<DIV style="MARGIN: 0px"><FONT style="FONT: 12px Helvetica"
face=Helvetica size=3>-- it has a fifth dimension for gridded data
sets?/font></DIV>
<DIV style="MARGIN: 0px"><FONT style="FONT: 12px Helvetica"
face=Helvetica size=3>-- internal data handling is all double
precision?/font></DIV>
<DIV style="MARGIN: 0px"><FONT style="FONT: 12px Helvetica"
face=Helvetica size=3>-- undef handling is cleaner</FONT></DIV>
<DIV style="MARGIN: 0px"><FONT style="FONT: 12px Helvetica"
face=Helvetica size=3>-- the netcdf/hdf interface has been
streamlined?/font></DIV>
<DIV style="MARGIN: 0px">-- the executable names are different:?/div>
<DIV style="MARGIN: 0px"> ??gradsc, gradsnc, and gradshdf are merged
into 'grads'</DIV>
<DIV style="MARGIN: 0px"> ??gradsdods is now 'gradsdap'</DIV>
<DIV
style="MIN-HEIGHT: 14px; MARGIN: 0px; FONT: 12px Helvetica"><BR></DIV>
<DIV style="MARGIN: 0px"><FONT style="FONT: 12px Helvetica"
face=Helvetica size=3>Because of these changes, and others that are
still in the works but haven't been implemented yet, there are some
features which we can no longer support. The UDF interface is disabled,
but will be return soon in a new implementation that should be easier to
use. The lterp() function (a widely used UDF) is now built-in. The LATS
interface is gone, but implementing a new path for writing out netcdf
with 'gxout fwrite' is very high on our to-do list. Templating with the
'sdfopen' command is also no longer supported, and some special cases of
binary file formats are now a legacy: "var" and "z" transposed data
(units=-1,1) and "x" and "y" transposed data (units=-1,30). The format
of the GrADS metafile will also change, as graphics improvements are
implemented. The gv utility will not work with GrADS 2.0. Otherwise, for
now, everything you do with GrADS should work in version
2.?/font></DIV>

face=Helvetica size=3>I have posted the source code and two binary
tarballs in:</FONT></DIV>

<DIV style="MARGIN: 0px"><FONT style="FONT: 12px Helvetica"
face=Helvetica size=3>Binaries are for RedHatEnterpriseLinux5 (x86_64)
and Intel Macs. If you are using GrADS on a unix platform of a different
flavor, I highly recommend trying to build from source, since I will be
posting updates to the source code very frequently. A list of the
required supplemental libraries is in the documentation at <A

style="COLOR: #0020e2"
color=#0020e2><U>http://iges.org/grads/gadoc/supplibs.html</U></FONT></A>
. Almost all of these supplibs are upgrades from previous versions and
build easily. I will update this doc page with additional guidance for
building from source as soon as I can.?/font></DIV>
