reneefredensborg/DIR-from-IS2: Estimating elevation anomalies (ridge sails) and degree of ice ridging (DIR) from ICESat-2 (IS2) (Version v1.1) R. M. Fredensborg Hansen

Short summary
Ice navigators rely on timely information about ice conditions to ensure safe passage through ice-covered waters, and one parameter, the degree of ice ridging (DIR), is particularly useful. We have investigated the possibility of estimating DIR from the geolocated photons of ICESat-2 (IS2) in the Bay of Bothnia, show that IS2 retrievals from different DIR areas differ significantly, and present some of the first steps in creating sea ice applications beyond e.g. thickness retrieval.
