Grid Analysis and Display System
The online (html) version of the GrADS documentation has become the standard base documentation for GrADS. Follow the links below to the Users Guide, an introductory tutorial session, and an alphabetical subject index. Note the documentation is covered under the same copyright as the GrADS source code.
The Users Guide is the fundamental document that provides information about how to use GrADS. The four main chapters are General Topics, Analysis Topics, Display Topics, and the GrADS Scripting Language.
The tutorial will give you a feeling for how to use the basic capabilities of GrADS. This sample session takes about 30 minutes to run through. It is highly recommended for new users. (En Español.)
The Index provides a quick and easy interface for checking the syntax and usage of any GrADS command or function. Subject headings from the User′s Guide are also listed in the Index.
You can download a compressed tar file containing
all the html source code. These can be useful to install on your local
computer if you have a slow internet connection or if you travel often
with a laptop.
