Seasonal climate forecast model within this system is currently built upon the ensemble of general circulation model or Global Climate Model (GCM) from the North American Multi-model Ensemble (NMME) of NOAA. For future development, it is also possible to couple the model with other sources like APEC Climate Center (APCC). The data serve as an input to Climate Prediction Tool for seasonal climate forecast within this system. Observation data from Badan Meteorologi, Klimatologi dan Geofisika (BMKG) and CHIRPS are used for validation to the outputs of climate forecast. Rainfall prediction is made available for location-specific in grid 5 x 5 km.
Forecast is run in Climate Predictability Tool (CPT). Forecasts are classified into two types:
