What Exectuable Files are in a Release?
Beginning with GrADS version 2.0.a8, there is only one fully-featured GrADS executable:
Reads GRIB (version 1 and 2), gridded binary, BUFR, GrADS station data, NetCDF (classic and NetCDF-4), HDF4-SDS, HDF5, and OPeNDAP (grids and station data)
The GrADS executables for version 2.0.a0 through 2.0.a7 are as follows:
Reads GRIB1, GRIB2, gridded binary, BUFR, GrADS station data, NetCDF, HDF-SDS;
Writes gridded binary and NetCDF
|gradsdap||Reads GRIB1, GRIB2, gridded binary, BUFR, GrADS station data, NetCDF, HDF-SDS, and OPeNDAP (aka DODS); Writes gridded binary and NetCDF|
The GrADS exectuables for versions 1.9 and earlier are as follows:
Reads GRIB, gridded binary, BUFR, GrADS station data
Reads GRIB, gridded binary, BUFR, GrADS station data, NetCDF
Writes GRIB, NetCDF
Reads GRIB, gridded binary, BUFR, GrADS station data, NetCDF, HDF-SDS
Writes GRIB, HDF-SDS
Reads GRIB, gridded binary, BUFR, GrADS station data, NetCDF, OPeNDAP (fka DODS)
Writes GRIB, NetCDF
External utilities are packaged in the binary distributions for all versions of GrADS (with exceptions as noted):
|gribmap||"Maps" a GRIB data set to a GrADS descriptor file|
|gribscan||Extracts grid and variable info from a GRIB data set|
|grib2scan||Extracts grid and variable info from a GRIB2 data set (only in version 2.0+)|
|bufrscan||Reads BUFR messages and prints out ascii values (only in version 1.9+)|
|gxps||Converts GrADS metafiles to Postscript (only in version 2.0.2 and earlier)|
|gxeps||Converts GrADS metafiles to Encapsulated Postscript (only in version 2.0.2 and earlier)|
|gxtran||Displays metafiles(only in version 2.0.2 and earlier)|
|stnmap||Maps station data|
|wgrib||See the wgrib home page|
The MS windows versions are packaged with an install script. For the UNIX versions, you must uncompress and unpack the tar file after you've downloaded it:
gunzip <tarfile>.gztar xvf <tarfile>
The GrADS executables are typically placed in
/usr/local/bin/grads/. If you do not have write permission for this directory, you can put them in a subdirectory of your home directory (
~/bin) or anywhere else in your path.
/usr/local/lib/grads/.If you do not have write permission for this directory you can place the files elsewhere, but you must also change the environment variable
GADDIRso the GrADS executables will know where to find these files. You can download the data files separately by clicking here:
cd <dirname>tar xvfz data2.tar.gzsetenv GADDIR <dirname>
An additional supplementary tar file contains a sample gridded data set along with an example session that reviews basic GrADS capabilities. This data set is not required to run GraDS. If you have not used GrADS before, you are strongly encouraged to obtain this file and go through the sample session. You can download it directly by clicking here:
If you are a MS Windows user, you may also want an executable of cnvgrib or wgrib2.

To view a GrADS metafile simply double click on a filename listed in the File Manager or Explorer, drag and drop the file onto GV, or use the standard Open dialog box. GV assumes that default extension of GRADS metafiles is GMF. If your file includes more than one picture you can browse through pages using the keyboard keys (PageDown and PageUp) or the toolbar buttons.
Use the View commands and the View/Options dialog box to customize the image -- display it as black-and-white or color, change the line thickness, or clip and enlarge any part of the image. Use the right mouse button to access the most commonly used features.
There are two ways to save separate pages of a GRADS metafile as Windows Metafile (WMF): 1) use the File/Save Page As command, or 2) use the Edit/Copy command to copy the current page to the Windows Clipboard and thenEdit/Paste it in your favorite Windows application that handles Windows Metafiles.
Use File/Print command to print a current document to any printer (you do not need a Postscript printer). Use File/Print Preview to display the active metafile as it would appear when printed
