The Arctic Surface Roughness # 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 sea ice surface roughness while still containing enough point measurements for robust # statistical calculations. Statistics are computed on the distribution of sea ice surface roughness for 10 km along-track segments, for each aircraft # flight line. # # Citation: # Users are asked to cite the following publication whenever these data are used: # Connor, L., S. Farrell and D. McAdoo (2017), A decadal study of interannual variability in Arctic sea ice freeboard using airborne laser altimetry # (2006-2016), presented at the 2017 IGS International Symposium on Polar Ice, Polar Climate, and Polar Change, Boulder, Colorado, 14-19 Aug. 2017. # # Point of Contact: Laurence.Connor@noaa.gov # # Data Product Webpage: https://www.star.nesdis.noaa.gov/sod/lsa/SeaIce/SeaIceSurfaceRoughness.php # # File format is comma separated ascii text, and columns are as follows: # 1.
