Project title: Ocean Reanalysis Algorithms for Climate Studies
Acronym: ORACS
Duration: 01/09/2024-31/08/2026
Project budget: € 200.000,00
ISMAR budget: € 58.900,00

Summary:
This project will develop improved algorithms to produce long term ocean reanalyses in the presence of varying observational networks. The project will focus on consistency of climate relevant metrics across 2 periods of increasing observational coverage, in the 1950’s and more in situ observations become available, and in the 1980s-90s as altimeter observations become available. It will test the role of different atmospheric forcing and riverine inputs. The project will develop improved ensemble error covariance approaches suitable for both sparse and more dense observing networks. It will also address the detection of bias in the assimilated results and make recommendations on how best to treat bias under varying observational conditions. Finally the project will apply new post-processed smoothing methods to more fully use observations and to spread information back to influence more sparsely observed periods. A set of Recommendations will be made to Copernicus Marine Service to aid in the production of a climate-consistent long period ocean reanalysis in the final report.
