The Unified Forecast System Subseasonal to Seasonal prototype 5 (UFS S2Sp5) dataset is reforecast data from the UFS atmosphere-ocean coupled model experimental prototype version 5 produced by the Medium Range and Subseasonal to Seasonal Application team of the UFS-R2O project. The UFS S2Sp5 is the first dataset released to the broader weather community for analysis and feedback as part of the development of the next generation operational numerical weather prediction system from NWS. The dataset includes all the major weather variables for atmosphere, land, ocean, sea ice, and ocean waves.
Acknowledgment - The Unified Forecast System (UFS) atmosphere-ocean coupled model experimental version 5 (UFS S2Sp5) data used in this study are made available through the UFS Research to Operations (UFS-R2O) project sponsored by the National Weather Service (NWS) Office of Science and Technology Integration (OSTI) Modeling Program Division and the National Oceanic and Atmospheric Administration (NOAA) Oceanic and Atmospheric Research (OAR) Weather Program Office (WPO).
Prototype 5 is a retrospective run for the period from 2011 to 2018. The runs are initialized twice per month (1st and 15th) and the length of the forecast is 35 days with an output frequency of 6 hours.
