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). Model simulations are made using the Dynamic Water Quality Model (DynQual). Concentrations only calculated when (gridded) channel storage >10m3.
