On Monday, 11 July from 3:00 p.m. through Wednesday, 13 July until 5:00 p.m. (USA Mountain Time), NSIDC data distribution, services, and Web site will be unavailable to accommodate a major upgrade to our data center.

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.
Both maps are adapted from:
