AI model AIFL enhances global streamflow forecasting accuracy

Researchers have developed AIFL, a novel LSTM-based model for global daily streamflow forecasting. This model employs a two-stage transfer learning approach, first pre-training on ERA5-Land reanalysis data and then fine-tuning on operational Integrated Forecasting System (IFS) data. This method effectively bridges the performance gap between historical reanalysis and operational forecast products. AIFL achieved a median modified Kling-Gupta Efficiency (KGE') of 0.66 and a median Nash-Sutcliffe Efficiency (NSE) of 0.53 on an independent test set, demonstrating comparable accuracy to existing state-of-the-art global systems.
