NCL allows users to change contour line thicknesses via 'cn' (contour)
resources.

*http://www.ncl.ucar.edu/Document/Graphics/Resources/cn.shtml*
<http://www.ncl.ucar.edu/Document/Graphics/Resources/cn.shtml>

See:   *cnLineThickness* *cnLineThicknesses*

Further, you can  go to * http://www.ncl.ucar.edu/Applications/*
<http://www.ncl.ucar.edu/Applications/>

Then where it says:

List of tips <http://www.ncl.ucar.edu/Applications/concepts_list.shtml>,
*resources
<http://www.ncl.ucar.edu/Applications/res_list.shtml>*, functions/procedures
<http://www.ncl.ucar.edu/Applications/func_list.shtml> and the example
scripts they appear in. List of NCL application example categories in
alphabetical order. <http://www.ncl.ucar.edu/Applications/list_alpha.shtml>

Click *resources*, then search for  *cnLineThickness *and  *cnLineThicknesses
*for examples that use those resources + example plots.
