As part of the periodic update of the geothermal energy assessments for the USA (e.g., last update by Williams and others, 2008), a new three-dimensional temperature map has been constructed for the Great Basin, USA. Williams and DeAngelo (2011) identified uncertainty in estimates of conductive heat flow near land surface as the largest contributor to uncertainty in previously published temperature maps. The new temperature maps incorporate new conductive heat flow estimates developed by DeAngelo and others (2023). Predicted temperatures at depth are compared with representative measurements (for conductively dominated conditions), showing good agreement under relatively simple uniform conditions. Inputs included radiogenic heat production for all layers of 1.89 μW/m3, effective bulk thermal conductivity of 2.7 W/m/°C for all rocks underlying sedimentary basins, and a previously published (Williams and DeAngelo, 2011) empirically driven estimate of increasing thermal conductivity with depth in sedimentary sequences. The resulting three-dimensional temperature model is presented in this data release. Version 1.1 corrects a minor coding error for generation of the thermal profiles. For version 1.0, the code had the following error: thermal conductivity at the reference temperature (zero) was allowed to vary in equation (3) of the documentation, but thermal conductivity was held constant value of 2.7 in the computation of the coefficient “b” (see paragraph following equation (3)). The new 3D temperature model was re-verified using the procedure described in the manuscript (i.e., Fig 7 was reconstructed and checked to ensure no bias or regionalization). Files that were updated for version 1.1 end with '_v1_1.'
