Re: Tropopause overlay

To my knowledge, no graphical options.

use, say, a 1-2-1 smoother or a 5 pt smoother

wgt = (/1,2,1/)*1.0
wgt = (/1, 3, 5, 3, 1/)*1.0

trop = wgt_runave(trop, wgt, 1)
http://www.ncl.ucar.edu/Document/Functions/Built-in/wgt_runave.shtml

This might be more convenient,

trop = wgt_runave(trop, wgt, 1, ???)
