Southern Ocean high-resolution model

Validating high-resolution Southern Ocean ice shelf melt against satellite data

Validating modeled ice shelf melt against satellite data is a necessary but humbling exercise. Our Southern Ocean high-resolution model, SOhi, overestimates melt, a discrepancy rooted in warm initial conditions, bathymetric uncertainties, and the limits of the satellite estimates themselves. Yet the model maps melt around Antarctica with unmatched detail, capturing intense melting near grounding lines. These gaps are not failures; they are a roadmap for better physics, sharper observations, and more integrated data ecosystems.
