The "Sea Ice Age and Drift" project will deliver the first global, long-term Climate Data Records for sea-ice age and drift, spanning the satellite era since the late 1970s. It will combine Lagrangian tracking with satellite-based classification to generate a hybrid sea-ice-age algorithm, extend drift records before 1991, and integrate multi-sensor data from passive microwave and scatterometer missions. Machine learning will enhance performance under challenging conditions such as melt–refreeze cycles and pancake ice regions. Products will be validated with in different data, include uncertainty estimates, and be applied in case studies to advance sea-ice research and climate model evaluation.
