Future monthly discharge and water temperature simulations under global change (CMIP6)

Monthly discharge (m3 s-1) and water temperature (K) simulated by a global hydrological model coupled to a surface water quality model (PCR-GLOBWB2-DynQual) for the time period 2005 - 2100, for an ensemble of 15 projections based on three combined climate and socio-economic scenarios (SSP1-RCP2.6; SSP3-RCP7.0 and SSP5-RCP8.5) and five general circulation models (GFDL-ESM4; UKESM1-0-LL; MPI-ESM1-2-hr; IPSL-CM6A-LR and MRI-ESM2-0)

Output data are provided at 10km resolution and are averaged at monthly temporal resolution.

These datasets were generated as part of the work presented in: Jones, E.R., Bierkens, M.F.P., van Puijenbroek, P.J.T.M. et al. Sub-Saharan Africa will increasingly become the dominant hotspot of surface water pollution. Nat Water 1, 602–613 (2023). https://doi.org/10.1038/s44221-023-00105-5
