Description
Global ~10km (5 arcmin) output data from the dynamical surface water quality model (DynQual) from 1980-2019, with annual and monthly temporal resolution. Simulations are made following the ISIMIP3a protocol (https://protocol.isimip.org/#/ISIMIP3a).
Output data includes:
- Discharge (m3 s-1)
- Channel storage (m3)
- Water temperature (K)
- Total dissolved solids (TDS) load (g s-1)
- Biological oxygen demand (BOD) load (g s-1)
- Fecal coliform (FC) load (million cfu s-1)
- Salinity; as indicated by TDS concentrations (mg l-1)
- Organic pollution; as indicated by BOD concentrations (mg l-1)
- Pathogen/bacterial pollution; as indicated by FC concentrations (cfu 100ml-1)
Note. a minimum discharge threshold of 0.1 m3 s-1 was used when computing salinity (TDS), organic (BOD) and pathogen (FC) concentrations, as uncertainties in absolute values of water availabilities have large impacts on resulting in-stream concentrations. Thus, if the the average discharge for the month was below 0.1 m3 s-1, concentrations are not calculated (assigned as NA).
In-stream water quality aggregated to 0.5 degree (i.e. 30 arcmin) spatial resolution (daily, monthly and annual) can be found at: https://zenodo.org/records/14675270.
