Mary,

It made the titles disappear altogether and the plot area was filled by a
jumbo-sized diagram - regardless of what vpWidthF value I specified. I'd
rather expect this to happen gsnMaximize = True rather than gsnMaximize =
False, but who knows...

Sure - I now also uploaded the data (and updated the script to match the
new file name):

http://bi.offis.uni-oldenburg.de/wrf_contour/

(frame_1c.jpg shows the result of gsnMaximize = False)

Indeed. I tried to study the WRFUserARW.ncl code (and files included
recursively). I would probably manage to find out how to hack it, but it
seems like a great effort for a small improvement. In the end, I just gave
up and shortened the title to make the plots look about right for the
scheduled presentation, but I thought it'd be interesting to find out how
to do it right next time.

I can also wait until the functionality makes it into the official
documentation :-)
