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. # # Citation: # Users are asked to cite the following publication whenever these data are used: # Duncan, K., Farrell, S., Connor, L., Richter-Menge, J., Hutchings, J., & Dominguez, R. (2018). High-resolution airborne observations of sea-ice # pressure ridge sail height.
