A description of model intercomparison processes and techniques for ocean forecasting

Fabrice Hernandez, Marcos Garcia Sotillo, and Angélique Melet

Data sets

ERA5 monthly averaged data on single levels from 1940 to present H. Hersbach et al. https://doi.org/10.24381/cds.f17050d7

Short summary

An historical review over the last 3 decades on intercomparison projects of ocean numerical reanalysis or forecast is first proposed. From this, main issues and lessons learned are discussed in order to propose an overview of best practices and key considerations to facilitate intercomparison activities in operational oceanography.
