# 75y Streamflow Reanalysis

1. We produced daily streamflow reanalysis for 1948-2022 by calibrating ILDAS with observed streamflow at 173-gauge stations over South Asia
2. The model showed overall good performance at daily (national median KGE = 0.45) and monthly (national median KGE = 0.60) time steps for 1981-2020,
3. The hydrologic signatures of calibrated ILDAS-reconstructed streamflow data show that the mean annual flow had the highest R2 score, and the mean annual low flow had the lowest, highlighting the need for incorporating anthropogenic effects into the model.
