[ncl-talk] Bug in gsn_csm_contour_map for MPAS?

[David Brown]

Hi Nick,
I ran your code (at least for long enough to get 8 plots) with the
development version of NCL and the problem seems to be fixed now.
There have been a few tweaks to the contour plotting code that may
have cleared up this issue. I am attaching one plot.

You can run the development version of NCL on yellowstone using the
following instructions from Mary Haley:

NCL V6.4.0 hasn't been released yet, but we do a nightly build of
6.4.0 *beta* that you are free to try.
On yellowstone/geyser/caldera you can get the nightly build by adding
the following to your MODULEPATH:
setenv MODULEPATH /glade/apps/contrib/ncl-nightly/modules:${MODULEPATH}
or
export MODULEPATH=/glade/apps/contrib/ncl-nightly/modules:${MODULEPATH}

You can do this in one of your ~/.* files, like "~/.bashrc",
~/.tcshrc, or ~/.profile. It depends on what file you normally use to
set environment variables.

Now, every time you login, you can type this to load the test version:

module load ncltest

To double-check that you have the latest version of NCL loaded:

ncl -V

This should echo a timestamp from the early morning, like:

6.4.0-20Sep2016_0113
