Experimental version of SMOS Antarctic Sea ice thickness product is now available

27 Nov 2023

The experimental version of the SMOS Antarctic Sea ice thickness product was produced using a method to derive the sea-ice thickness from 1.4 GHz brightness temperatures previously developed for the Arctic, with only modified auxiliary data.

The product is available in the cold season during the freezing period, typically March to October for the Southern Hemisphere. The experimental product is now available on the SMOS dissemination service. The validation paper is under review, a preprint is available.
