	            This data set contains spot elevation measurements of Greenland, Arctic, and 
	            Antarctic sea ice acquired using the NASA Airborne Topographic Mapper (ATM) 
	            4CT3 narrow scan instrumentation. The data were collected as part of Operation 
	            IceBridge funded aircraft survey campaigns.
