This is the modelled basal melt rates and modelled basal temperature relative to the pressure melting point in ten experiments using different geothermal heat flux (GHF) maps as forcing for an offline coupling between a forward thermal model and an inverse mechanical model. The forward model consists of a thermomechanical steady state model using an improved shallow ice approximation in equilibrium with the subglacial hydrological system. The inverse model is solved using 3D full Stokes model. Eight GHF maps are from Martos et al. (2017), Purucker (2012), Shen et al. (2020), An et al. (2015), Shapiro and Ritzwoller (2004), Stål et al. (2021), Lösing et al. (2021) and Haeger et al. (2022). The other two maps are mean GHF and constant GHF. Mean GHF is the ensemble mean of the 8 GHF datasets above interpolated into 2.0 km resolution. The constant GHF is the mean of the ensemble mean GHF, 59 mW m-2. For the modelled results using GHF map from the 8 datasets, the filename includes the family name of the first ...
