In the tools directory models/lnd/clm/tools/ncl_scripts and in a few other locations there are scripts that use NCAR Command Language (NCL). Unlike the FORTRAN tools, you will need to get a copy of NCL in order to use them. You also won't have to build an executable in order to use them, hence no Makefile is provided. NCL is provided for free download as either binaries or source code from: http://www.ncl.ucar.edu/. The NCL web-site also contains documentation on NCL and it's use. These scripts are stand-alone and at most use environment variables to control how to use them. In some cases there are perl scripts with command line arguments that call the NCL scripts to control what they do.
