Contribution of future wide-swath altimetry missions to ocean analysis and forecasting [PDF]

Ocean Science, 2018
The impact of forthcoming wide-swath altimetry missions on the ocean analysis and forecasting system was investigated by means of OSSEs (observing system simulation experiments). These experiments were performed with a regional data assimilation system,

Assimilation of wide-swath altimetry water elevation anomalies to correct large-scale river routing model parameters [PDF]

Hydrology and Earth System Sciences, 2020
Land surface models combined with river routing models are widely used to study the continental part of the water cycle. They give global estimates of water flows and storages, but they are not without non-negligible uncertainties, among which inexact ...
