Synergistic Observing Network for Ocean Prediction (SynObs)

SynObs will seek to extract maximum benefit from combining various observation platform measurements, typically satellite and in situ observation data, or combinations of coastal and open ocean platforms for ocean/coastal predictions.

SynObs aims to identify the optimal combination of the different ocean observation platforms through observing system design and evaluation, and to develop assimilation methods which can enable drawing synergistic effects from these combinations. Targets of SynObs include open-ocean, such as global, tropical, mid-latitude, arctic and subarctic oceans, as well as coastal-sea, and biogeochemical observing systems.


SynObs has now been endorsed as UN Decade Project


SynObs was officially launched at the Joint OS-Eval TT/CP-TT workshop in Tsukuba, Japan, 15-18 Nov 2022


SynObs original proposal

SynObs as a project of ForeSea was submitted to the UN Decade second call for action in Jan 2022.

The submission document can be viewed here.
