New Sea Ice Pressure Ridge Sail Height Product Available
Oct 10, 2019
A new Sea Ice Pressure Ridge Sail Height product from NOAA is now available in the PolarWatch ERDDAP. Sail height data is derived from high-resolution airborne imagery acquired during NASA's annual Operation IceBridge campaigns in the Arctic (2010-2018). Pressure ridges impact mass, energy, and momentum budgets of sea-ice cover and present an obstacle to transportation through icy waters. Quantifying ridge characteristics is important for understanding total sea-ice mass and for improving sea-ice dynamics in high-resolution models.
