circular pcolor map (looking down on the north pole)

How can I produce a circular pcolor map (looking down on the north pole) ?

Your map needs to begin and end with the same color. Beyond that, you'll have to provide some more information.

h=pcolor(LON,LAT,Final);

I am using this command of pcolor which is very common. I want to make a spatial map using pcolor like this, find the attachment.

Apologies; I completely misinterpreted the question.
