Sea Ice Surface Elevation from Ice Bridge Airborne Surveys, Arctic

Summary

This is airborne sea ice surface elevation data from annual Ice Bridge surveys spanning from 2009-2018. Data are derived from Airborne Topographic Mapper (ATM) lidar elevation data. PolarWatch hosts 1-km along track resolution data, much higher resolution data is available directly from NESDIS and is linked below.

Dataset Description

This dataset contains the NOAA / NESDIS / STAR / LSA Polar Ocean Data System (PODS) Arctic Gridded Surface Elevation Product. 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 between March and May, 2009 - 2019. 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 (See Figure 1 on Data Product Webpage). 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 providing high-resolution measurements of elevation while still containing enough point measurements for robust statistical calculations.
