Qualité des mesures du niveau des cours d'eau par altimétrie satellitaire radar: influence de l'hydrologie des cours d'eau, de la précision et de la fréquence d'échantillonnage des mesures

[Notes_IRSTEA]un poster [Departement_IRSTEA]DS [TR1_IRSTEA]METHODO / SYNERGIEDuring the past 15 years, Satellite Radar Altimetry (SRA) have shown its potential contribution for monitoring river water levels. But nowadays, it is still not operational because the quality of SRA time series is not yet systematically quantified, and moreover because not any methodology have ever been defined. In this study, we wish to introduce efforts we have done toward a standardized methodology for quantifying the quality of the SRA derived times series. This framework aims to be used on SRA data sets from various configuration, produced by various altimetry research teams.Poster présenté lors du congrès EGU à Vienne en 2006
