Data Requirement:
The ISO hindcast experiment requires aset of retrospective ISO forecasts, which covers the last 20 years from 1989 to 2008. The minimum (standard) specification of the hindcast are: (a) Prediction is initiated every 10 days on 1st, 11st, and 21st of each calendar month throughout the entire 20-year period: (b) Integration length for each forecast is 45 days; (c) The number of ensemble for each forecast is at least 5. The free coupled run or AMIP-type run is served as control experiment for better understanding the dependence of the prediction on initial conditions and better defining metrics that measure the "drift" of the model toward their intrinsic MJO/Monsoon ISO modes. Currently, 11 modeling groups have finished their experiment.
Current Status:
11 models' hindcasts have been collected from EC, GFDL, NCEP and UH in North America, CMCC, and ECMWF in Europe, CWB, JMA, SNU, and PNU in Asia, and ABOM in Australia. There are nine one-tier and two two-tier prediction system.
