The Global Deterministic Prediction System (GDPS) is a coupled atmosphere (GEM), ocean and sea ice (NEMO-CICE) deterministic numerical weather prediction model where the GEM-predicted large-scale temperature and horizontal wind components are spectrally nudged toward the Global Environmental eMuLator (GEML) predictions, ECCC's data-driven artificial intelligence (AI)-based weather model.
