Resolution
Spatial aggregation: subbasins
Horizontal resolution: 0.5°x0.5°
Temporal resolution of input data: climate variables: daily
Temporal resolution of input data: soil: constant
Input data
Simulated atmospheric climate data sets used: IPSL-CM5A-LR, HadGEM2-ES, GFDL-ESM2M, MIROC5
Observed atmospheric climate data sets used: EWEMBI
Climate variables: tasmax, tasmin, pr
Spin-up
Was a spin-up performed?: Yes
Methods
Potential evapotranspiration: The VIC uses Penman-Monteith method to estimate potential evapotranspiration.
Vegetation
Is co2 fertilisation accounted for?: No
Routing
Runoff routing: The VIC model solves water and energy fluxes, grid by grid at daily time steps. A separate routing model is used to simulate discharge at different gauge locations.
Routing data: Shuttle Radar Topography Mission Digital Elevation Model (SRTM DEM) was used to prepare routing files (flow direction, flow fraction, flow mask and station files).
Calibration
Was the model calibrated?: Yes
Which years were used for calibration?: Godavari calibration (1980–1989) and validation (1990–1999). Yellow river calibration (1970–1974 and 1986-1990) and validation (1971-2000)
Which dataset was used for calibration?: Observed daily streamflow data and Satellite (MODIS and GLEAM) monthly actual evapotranspiration.
How many catchments were callibrated?: For Godavari basin - 4 gauge stations were calibrated. For Yellow basin - 3 gauge stations were calibrated.
Modelled catchments
Modelled catchments: Upper Godavari Yellow river basin.
