[ncl-talk] Polar stereographic plots of tripole grids

[Abigail Smith]

Hi NCL-talk,

I'm attempting to create polar stereographic contour plots of Arctic sea
ice from various CMIP models on their native grids. Some of the grids are
tripole, so I end up having the same gap as seen in ice_4.ncl at
https://www.ncl.ucar.edu/Applications/orca.shtml. I want to remove the gap,
but the solution in ice_4.ncl uses U-fold grid coordinates, which aren't
provided for many CMIP models.

I've attached an example script and the plot it produces. The data are
available for download here:
https://handle-esgf.dkrz.de/lp/21.14100/c55636b2-3c1a-4735-8243-4e62310acbc3
I'm running ncl version 6.3.0 and not getting any error messages.

Thanks in advance for considering this issue!

Best,
Abigail Smith
