Installing GrADS on Linux/MacOS X/Unix
Downloading the software
The GrADS binaries can be downloaded from sourceforge under package grads. In the same directory you will find file grads-$version-data.tar.gz which contains the fonts and map datasets. The OpenGrADS extensions for each platform are also found on sourceforge under package extensions.
Installing the binaries
The executables contained in the binary tar file are typically placed in the directory /usr/local/bin. If you do not have write permission for your /usr/local/bin directory, you can put them in the ~/bin subdirectory of your home directory.
cd /usr/local/bin gunzip tarfile.gz tar xvf tarfile
After unpacking the first tar file, you should have the following executables:
gradsc Classic GrADS - readline only gradshdf GrADS with NCSA HDF-4, LATS, GUI, SDF gradsnc GrADS with unidata netCDF-3, LATS, GUI, SDF gradsdods OPeNDAP-enabled GrADS with unidata netCDF, LATS, GUI, SDF gribmap "Maps" a GRIB data set to a GrADS descriptor file gribscan Extracts grid info from a GRIB data set bufrscan Reads BUFR messages and prints out ascii values gxeps Converts GrADS metafiles to Postscript gxtran Displays metafiles stnmap Maps station data wgrib See http://www.cpc.ncep.noaa.gov/products/wesley/wgrib.html
Installing the fonts and map datasets
The second tar file (grads-$version-data.tar.gz) contains the GrADS fonts and maps data sets is also necessary. The contents of this file 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 gunzip *.data.tar.gz tar xvf *.data.tar setenv GADDIR dirname (If dirname is not /usr/local/lib/grads)
