# Data Description:
# This data file contains the NOAA / NESDIS / STAR / LSA Polar Ocean Data System (PODS) Arctic Sail-Height Product. The Arctic Sail-Height
# Product is derived from high-resolution Digital Mapping System (DMS) imagery of sea ice pressure ridges acquired during annual, low-elevation
# NASA Operation IceBridge airborne surveys over Arctic sea ice. IceBridge observations were acquired between March and May, 2010 - 2018 incl.
# Statistics for pressure ridge sails are extracted per image. Arithmetic averages are computed for 25km along-track segments for each aircraft flight line.
