CESM2 SMYLE Multi-decadal Prediction Project

The CESM2 MDP (MultiDecadal Prediction) dataset is an initialized prediction system using CESM2. It consists of fully coupled initialized hindcast simulations using CESM2 component models at nominal 1 degree horizontal resolution. Hindcasts are initialized on November 1st from historical reconstructions (SMYLE-FOSI for ocean and sea-ice; Forced land only for land; and JRA55 reanalysis for atmosphere) and then integrated forward 242-months. Initialization occurs every 5 years from 1960 to 2015. The ensemble size is 10 for each start date, with ensemble spread introduced through a random field perturbation applied to the atmospheric initial conditions. The CESM2 MDP dataset is the multidecadal companion to the seasonal-to-multiyear CESM2 SMYLE (DOI: 10.26024/PWMA-RE41 [https://gdex.ucar.edu/datasets/d651065/]).
