Comparing Altimetry with Tide Gauges and Argo Profiling Floats for Data Quality Assessment and Mean Sea Level Studies

摘要: Altimeter missions have provided accurate measurements of sea surface height since 1992 not only with TOPEX/Poseidon but also Jason-1, Envisat, and recently Jason-2. The overall quality assessment altimeter data can be performed by analyzing their internal consistency the cross-comparison between all missions. In this study, in situ are used as an external, independent reference to enable further level. most up-to-date assessed compared those from tide gauges Argo profiling floats. first focus is on detection global regional drifts measurements. A second point that method assess impact new standards (e.g., orbit solution, instrumental correction, retracking algorithm) thanks observations. Finally, study shows how multiple reliable products detect potential anomalies ...
