The graphics generated for the local areas are exact subsets of the hemispheric grids' data, on the same grid. The resolution is unchanged from the full grid's, 12.7 km on a polar stereographic grid true at 60 N. The reference longitude is 80 W in both hemispheres.

The Alaska grid moves with the changing ice season, but the other grids are fixed. The Antarctic graphics are only displayed during certain times of year -- those when there may be something interesting occurring.

Corner point locations, in both latitude-longitude and i,j values, are given below. The i,j are in from the hemispheric grid, and start counting at 0 (C-like references).
