Dataset for real-time daily ensemble streamflow forecasting across a rainfed river basin using a Bayesian hierarchical model combination framework

This dataset contains the files with time series of potential covariates, daily peak monsoon (July-August) streamflow used to post-process daily VIC streamflow forecast across the Narmada River basin network, India, for the period calibration (2003-2018). It also contains a file with basic information (longitude, latitude, and area) for the gauges considered here and observed data and covariates at the Handia gauge for the peak monsoon season 2021. The potential covariates comprise daily VIC forecasted (1- to 10-day lead time) and simulated streamflow from each gauge, and 1, 2, 3, and 4-days accumulated spatial average observed precipitation from the area between the station gauges from 1 to 10-day lead times. The observed streamflow and gridded precipitation data were obtained from the India Water Resources Information System (India-WRIS) and the India Meteorology Department (IMD). Then, data were processed to obtain the dataset presented here.
