Abstract
- International audience; Rapid sea level signals are poorly resolved, or "aliased," by the TOPEX/Poseidon altimeter, due to its ∼10-day repeat cycle (Nyquist period TN∼ 20 days). To assess the potential for temporal aliasing in the altimeter data, the authors analyze hourly sea level records from a set of 110 island and coastal tide gauges. Time series are detided to focus on nontidal effects. Large variance is found at periods
