Changes:

  • 01-09-2020: Extension of the reforecast period from 1991-2010 to 1991-2016.
  • 01-08-2020: Nine additional parameters allowing computing MJO indices were added  to the KMA outputs starting from 1  August 2020 for the real-time forecasts and from 1 September for the on-the-fly reforecasts:
    • Snow Fall water equivalent
    • Surface net solar radiation
    • Surface net thermal radiation
    • Surface solar radiation downwards
    • Surface thermal radiation downwards
    • Top net thermal radiation
    • Sea surface temperature
    • Total Cloud Cover
    • Specific humidity (on pressure levels)
  • 31-10-2017:  In reference to Tennant(2013), the soil moisture content(SMC) and surface temperature perturbations were added to KMA’s Global Ensemble system. It should improve predictive performance of the surface variations that have a smaller spread than the upper level one. Together with SST perturbation, it helps improving the spread of surface temperature and moisture.
