The data has been summed spatially over a 5 degree by 5 degree grid and temporally over intervals of 15 degrees of solar longitude. The SGS product data is presented in a tables corresponding to the 36 latitude bands of the 5x5 degree grid. This file is for the band centered at 87.5 degrees latitude. Within each band, longitude increases eastward from the cell centered at 2.5 degrees east longitude to the cell centered at 357.5 degrees east longitude. 54 1 131356 AREOCENTRIC_LATITUDE 1 1 IEEE754MSBSingle 4 degrees Centerpoint areocentric latitude.
