Re: [ferret_users] Shifting the pole

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi Bijoy,
I guess it depends on how you want to do this. Do you have in mind some 
way to make the transformation?  Ferret can handle visualizations of 
data on grids that are defined in terms of curvilinear coordinates, see
http://ferret.pmel.noaa.gov/Ferret/documentation/users-guide/customizing-plots/MAP-PROJECTIONS-AND-CURVILINEAR-COORDINATES#Chapter6-Map_Projections

There are for instance tri-polar grids (e.g. 
http://climate.gmu.edu/poseidon/code/Tripole.html) that people use to 
put the pole over onto land masses.
