Sea Ice Surface Elevation derived from Airborne Topographic Mapper (ATM) lidar elevation data, Arctic, 2009-2018 (NCEI Accession 0237069)
The gridded Surface Elevation product is derived from Airborne Topographic Mapper (ATM) lidar elevation data acquired during annual, low-altitude NASA Operation IceBridge airborne surveys over Arctic sea ice. IceBridge ATM data were acquired from March 2009 to May 2018. Due to the conical scanning geometry of the ATM lidar, across-track sampling is non-uniform, with sampling density greatest at the swath edges. To account for the variation in sample density, ATM elevation data are gridded. Each grid cell has an along-track dimension of 30 m and an across-track dimension that is inversely proportional to the across-track sampling density. The grid configuration optimizes ATM sample density which provides high-resolution measurements of elevation while it still contains enough point measurements for robust statistical calculations.
