There is a couple example MITgcm Arctic Ocean configurations here:

Hi All:

My apologies if I have been littering the support with unanswerable questions but
I appear to be at a conundrum.

My current objective is to try to get a spherical regional model to successfully work
at the North pole but I am at a loss. As far as I know, there exists a singularity
at latitude = 90N due to the spherical laplacian term in the Navier-Stokes
equation and hence convenctional lat-lon grids do not work.

Thus, I have read into using the exch2 package to determine if it is feasible to
get a regional model working at the North Pole. However, I am at a loss as I am
not familiar in setting up the data.exch2 file (for a single face) with a fixed lat-lon
domains (eg. 0E to 360E, 80N to 90N or 0E to 360E, -90N to -80N) with
dlat and dlon resolution (eg. dlat = 0.1,dlon = 0.1 resolution).

Does using the package exch2 provide a feasible method for regional
modelling at the poles? If so, how do I correctly set up the data.exch2 file?

Cheers,
Benjamin
