Remote sensing of ice conditions in the Southeastern Baltic Sea and in the Curonian Lagoon and validation of SAR-Based ice thickness products /
Here we analyze ice conditions in the Southeastern Baltic (SEB) Sea and in the Curonian Lagoon (CL) using spaceborne synthetic aperture radar (SAR) data combined with in-situ measurements from coastal stations during four winter seasons between 2009–2013. As shown, the ice conditions in the SEB and...
