comment:	"The MISR Level 3 Component Global Aerosol (CGAS) AerosolParameterAverage\\012grid fields summarize selected MISR Level 2 Aerosol parameters. The\\012Level 3 global summaries are reported on a rectangular, geographic\\012grid that is 0.5 degree latitude by 0.5 degree longitude. The lower\\012left corner of the grid is located at -90 S, -180 W. The center of the\\012lower left corner grid cell is at -89.75 S, -179.75 W."
