Global monthly averaged TDS, BOD and FC concentrations between 2021 and 2030 at 10km spatial resolution for 5 GCMs under two wastewater treatment scenarios.

Global 10km spatial resolution dataset for modelled total dissolved solids (TDS; mg/L), biological oxygen demand (BOD; mg/L) and fecal coliform (FC; cfu/100ml) averaged per month between 2021 and 2030 for 5 GCMs (GFDL, IPSL, MPI, MRI and UKESM) and under two wastewater treatment scenarios (no expansions in wastewater treatment vs. SDG6.3 attainment). <br> Model simulations are made using the Dynamic Water Quality Model (DynQual). Concentrations only calculated when (gridded) channel storage &gt;10m³.
