MPI-ESM-LR 1.2.01 inter-annual prediction hybrid localEnKF and ML ocean monthly and yearly

Beobide Arsuaga, Goratz; Brune, Sebastian

Dataset
Summary
Selected monthly mean and yearly mean ocean output of inter-annual predictions, based on the decadal prediction system with MPI-ESM-LR 1.2.01p5, 1.2.01p7, members 1 to 16, with machine learning modified initialisation state of the North Atlantic Ocean.
Hindcasts dmlen4YYYY_rXi2p3-LR with 16 members started November 1st each year 1960-2020, all running 26 months.
All simulations with CMIP6 external forcing.
Simulations have been planned by Sebastian Brune and Goratz Beobide Arsuaga (UHH). ML modifications according to Lentz et al. (2025) https://doi.org/10.1038/s41598-025-86374-4. Simulations have been run @DKRZ on Levante by Goratz Beobide Arsuaga (UHH) in 2025.
