Hindcast(JMA/MRI-CPS3) Configuration

A 30-year (1991-2020) hindcast with JMA/MRI-CPS3 is carried out in the same way as the real-time operational suite except for a small ensemble size of 10 for every initial month, which are composed of five-member ensembles started from two initial dates with 15-day intervals (Table 1).
