GrADS - Grid Analysis and Display System

GrADS Executables for UNIX
GrADS is distributed freely and is copyrighted under the GNU Public License.
Please read the COPYRIGHT file for more complete information.
For download information consult http://grads.iges.org/grads/downloads.html
The executables contained in this tar file are typically placed in the
directory /usr/local/bin. If you do not have write permission for your
/usr/local/bin directory, you can put them in the ~/bin subdirectory of your home
directory.
cd /usr/local/bin
gunzip tarfile.gz
tar xvf tarfile
After unpacking the first tar file, you should have the following executables:
grads GrADS - The basic package
gradsdap GrADS enabled to read data remotely via OPeNDAP
gribmap Creates an index file that "maps" a GRIB data set for a GrADS descriptor file
gribscan Extracts grid info from a GRIB data set
grib2scan Extracts grid info from a GRIB2 data set
bufrscan Reads BUFR messages and prints out ascii values
gxps Converts GrADS metafiles to Postscript
gxeps Converts GrADS metafiles to Encapsulated Postscript
gxtran Displays metafiles
stnmap Maps station data
wgrib See http://www.cpc.ncep.noaa.gov/products/wesley/wgrib.html
A second tar file (data.tar.Z) contains the GrADS fonts and maps data sets is
also necessary and can be downloaded from http://grads.iges.org/grads/downloads.html.
The contents of data.tar are typically placed in the directory
/usr/local/lib/grads, the default location for these files. If you do not have
write permission for /usr/local/lib/grads, you can place the files elsewhere, but
you must also change the environment variable GADDIR so the GrADS executables will
know where to find these files.
cd dirname
uncompress data.tar.Z
tar xvf data.tar
setenv GADDIR dirname (If dirname is not /usr/local/lib/grads)

<title>About the GrADS Documentation</title>

<body text="#000000">
<h1>About the GrADS Documentation</h1>
<p>
This html version of the GrADS documentation has become the standard
base documentation for GrADS. If you would like to download a
compressed tar file containing all the html source code, it is located
in the GrADS anonymous FTP directory. The most recent version was
posted on 1 May 2001:
<p>
<dd><a href="ftp://grads.iges.org/grads/gadoc_files.tar.Z">
ftp://grads.iges.org/grads/gadoc_files.tar.Z</a>
<p>
<p>
Although there are no immediate plans to produce a printed version of
the GrADS documentation, a limited set of html tags were used so that
a filter could be developed that would make it possible to create a
printed document from the html source code.
<p>
<p>
<h3>Tags Used</h3>
