Continuous SAR Ice‑speed Baselines

Use continuous synthetic‑aperture radar (SAR) time series as the standard operational baseline for glacier‑flow monitoring across Greenland and Antarctica so that ice‑sheet dynamics are tracked with daily/seasonal resolution rather than occasional snapshots. Regular, open SAR velocity products make it possible to detect abrupt doorstop failures, quantify dynamic thinning, and convert ice‑flux anomalies directly into updated local sea‑level projections. — If adopted as an operational public data product, continuous SAR ice‑speed baselines would provide immediate, evidence‑based triggers for coastal planning, national adaptation budgets, and international climate liability debates by turning glacier dynamics into auditable, policy‑actionable indicators.
