ECMWF global coupled atmosphere ocean and sea-ice dataset for the Year of Polar Prediction 2017–2020

摘要

Schematic of the YOPP dataset production framework: The initial conditions and ensemble forecasts are generated by ECMWF’s operational forecasting system based on ensembles of data assimilation and models. Atmosphere, land and ocean waves are separate from the ocean and sea-ice circulation in the data assimilation system, while the forecasts are fully coupled. Only the unperturbed control experiment output is ingested in the YOPP dataset from day 0 to day 15, and complemented by physical process tendency output from day 0 to day 2.
