When was the current long-range forecast system implemented?

System Name : GloSea6GC3.2
Implimented : Feb, 2022

Is it a coupled forecast system? Yes
Is it a Tier-2 forecast system? No 
Atmospheric model resolution

UM: N216L85
0.83 lon x 0.56 lat x 85 levels

Ocean model (if applicable)

eORCA Tri-polar grid at 0.25, 75 levels

Source of atmospheric initial conditions

Forecasts : KMA NWP

Hindcast : ERA-interim

Source of ocean initial conditions

Forecasts : KMA GODAPS2 (Global Ocean Data Assimilation System v2)

Hindcasts : UKMO ODA Reanalysis

If Tier-2, what is the source of SST predictions? N/A
Hindcast Period 1993-2016
Ensemble size for the hindcasts 28 members (from 4 different start dates)
How is the hindcast ensemble configured? Lagged approach, 7 members per start date on the 1st, 9th, 17th, and 25th, of each calendar month. All 7 member share the same initial conditions and differ only due to schemes to represent model uncertainties
Ensemble size for the forecast 84
How is the forecast ensemble configured? Lagged approach, 4 members per each date on 3weeks (21days)
Length of forecasts 6 months
Data Format GRIB 2
What is the latest date predicted anomalies for the next month/season become available? 13th of the month
How are the forecast anomalies constructed? Departures from the model climate estimated by the hindcast integrations
