This includes, in particular: • Dedicated products for the Baltic: ocean colour, sea level, coastal altimetry, salinity, and new dedicated Sentinel-2 products. • Characterisation of biochemical exchanges (land-sea and air-sea) including salinity dynamics. • Characterising and closing the water cycle of the Baltic. • 4D reconstruction of ocean dynamics by integration of EO and modeling of the Baltic Sea. • Characterising and predicting major Baltic inflows. Baltic+ Salinity Dynamics and Baltic+ SEAL (Sea Level) projects have contributed to these challenges by developing dedicated products of sea surface salinity (SSS) and sea surface height (SSH), respectively. Here, we will explore the potential synergy between both products with a twofold purpose: to perform an inter-validation of both products, and to explore the potentiality of both datasets to address some of the scientific challenges identified by ESA and the Baltic Earth community. We will first explore the detection and monitoring of the Atlantic salinity inflow and its recirculation inside the basin by presenting a preliminary assessment of the consistency between structures detected in Baltic+ Salinity SSS maps and circulation patterns derived from Baltic+ SEAL altimetry observations [2,3]. As an example of application, we will analyse how SSS and SSH reflect the mean flow condition across the Danish straits and how they react by local wind conditions and larger atmospheric circulation patterns[4]. While ideally the characteristics of the full water column would be needed, the combination of SSS and altimetry data can help monitoring the inflow and the distribution of surface waters characterised by different densities.
