A New Version of Regional Ocean Reanalysis for Coastal Waters of China and Adjacent Seas

摘要：

　　A new regional ocean reanalysis over multiple decades (1958 to 2008) for the coastal waters of China and adjacent seas has been completed by the National Marine Data and Information Service (NMDIS) under the CORA (China Ocean ReAnalysis) project.Evaluations have been performed on the improvement of general reanalysis quality and eddy structures.Results show that the quality of the new reanalysis is enhanced beyond ~40% (39% for temperature,44% for salinity) in terms of the reduction of root mean squared errors for which the reanalysis values are compared to the observed values in the observational space.Compared to the old version,the new reanalysis is able to reproduce more detailed eddy structures as seen in satellite and in-situ observations.These evaluations suggest that the new CORA regional reanalysis creates a much more useful dataset for the community of the coastal waters of China and adjacent seas.
