Fig. 2.1 - The PIRCS 60-km polar stereographic grid. Every second grid point of the inner domain is marked with a +; every second grid point of the outer domain (forcing frame) is marked with a o.
Orientation of the inner domain:
Central point      (X_28, Y_41) (37.50 N, 100.00 W)
Lower left corner  (X_1 ,  Y_1) (23.07 N, 117.79 W)
Upper right corner (X_55, Y_81) (45.41 N,  70.50 W).
