Long Description: The Grid Analysis and Display System (GrADS) is an interactive desktop tool that is used for easy access, manipulation, and visualization of earth science data. The format of the data may be either binary, GRIB, NetCDF, or HDF-SDS (Scientific Data Sets). GrADS has been implemented worldwide on a variety of commonly used operating systems and is freely distributed over the Internet.

If you haven't already installed Darwin Ports, you can find easy instructions for doing so at the main Darwin Ports page.
Once Darwin Ports has been installed, in a terminal window and while online, type the following and hit return:

%  cd /opt/local/bin/portslocation/dports/grads
%  sudo port install grads  
Password: 

You will then be prompted for your root password, which you should enter. You may have to wait for a few minutes while the software is retrieved from the network and installed for you. Y ou should see something that looks similar to:

--->  Fetching grads
--->  Verifying checksum for grads
--->  Extracting grads
--->  Configuring grads
--->  Building grads with target all

--->  Staging grads into destroot

--->  Installing grads

- Make sure that you do not close the terminal window while Darwin Ports is working. Once the software has been installed, you can find further information about using grads with these commands:

%  man grads
%  apropos grads
%  which grads
%  locate grads
