Over the last years, CryoSat-2 has provided several products, such as pan-Arctic sea ice thickness maps, dynamic topography and geostrophic currents, but Antarctica similar products have had a lower level of maturity since specific challenges in the processing of the radar signal result from the complex surface characteristics of Southern Hemisphere’s sea ice and ocean fields.

CryoSat+ Antarctica Ocean project objective is to address these issues by developing new approaches and algorithms that could be implemented in ESA’s CryoSat-2 ground segment processor to produce state of the art sea ice and ocean products that will be validated airborne and in-situ measurements and result in scientific progress for the understanding of the Antarctic climate system and ocean circulation.

isardSAT will participate in the Along Track product development and validation, and in the gridded product development and validation. isardSAT will also develop two lead detection methods, one using Fully Focused processing and the other using SARIn interferometry, as well as two retracker methods, one for sea ice and the other for ocean retrievals.
