North Polar SSM/I Grid

The Polar Gridded AVHRR Brightness Temperatures data set uses the same projection and grid as that used by NSIDC for the Arctic SSM/I data. The north polar SSM/I grid is aligned with the 135 degrees west 45 degrees east meridian. The Pacific and European Grids Map shows the two grids used to match this grid alignment.
