2018 IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium  
In this work, we consider the application of AnDA to the spatio-temporal interpolation of SLA (Sea Level Anomalies) from two types of satellite altimetry data, namely from along-track nadir data [1] and  ...  Results suggest an additional potential improvement from the joint assimilation of SWOT and along-track nadir observations.  ...  in the Western Mediterranean Sea from satellite altimetry data, considering different observation sampling patterns, with a view towards the upcoming SWOT altimetry mission.  ...

2021 Remote Sensing  
Its application is thus more efficient when the surface Chl evolution is not dominated by the biological activity, mostly occurring in the mid-February to mid-March time window in the Mediterranean Sea  ...  The study is focused on the Mediterranean Sea, where the most energetic signals are found at spatio-temporal scales up to 10 km and a few days.  ...  D.Ciani thanks Paolo Lazzari and Gianpiero Cossarini for the discussions on the analysis and forecast of the Mediterranean Sea biogeochemical state.  ...

The assimilated data include for example high-resolution SST surface radar (Yu et al., 2012) , along track altimetry (Kurapov et al., 2011) , temperature and salinity profiles from autonomous underwater  ...  The along-track resolution of traditional nadir alongtrack altimetry is not sufficient to capture variability on these scales and is not as useful as at mid-latitudes.  ...
