Abstract We provide grid files that collectively allow recreating 3D structural subsurface model of Brandenburg discussed in the papers (Noack, et al., 2010), (Noack, et al., 2012) and (Noack, 2013). The crustal-scale model covers an area of 250 km in E–W direction and 210 km in N–S direction and is located in the Northeast German Basin (NEGB). We provide ASCII files with top surface elevation and thickness of individual stratigraphic layers. There are two versions of the stratigraphic layering: one with the Rupelian clay layer and one without it. The coordinate system used is Gauss Krueger zone 4. The model without the Rupelian complements the following published papers: 1. Sensitivity of 3D thermal models to the choice of boundary conditions and thermal properties: a case study for the area of Brandenburg (NE German Basin).(Noack, et al., 2012). 2. Assessment of the present-day thermal field (NE German Basin)—Inferences from 3D modelling (Noack, et al., 2010) The model with the Rupelian is a complement to the publication of the paper: 1. Influence of fluid flow on the regional thermal field: Results from 3D numerical modelling for the area of Brandenburg (North German Basin) (Noack, et al., 2013). The provided structural model without the Rupelian consists of 15 layers starting from quaternary to the Lithosphere-Asthenosphere Boundary(LAB) and the one with the Rupelian consists of 17 layers starting from quaternary to the base (Moho). The files provided here include information on the regional variation of these geological units in terms of their depth and thickness, both attributes being allocated to regularly spaced grid nodes with horizontal spacing of 1 km. The model has originally been developed to obtain a basis for numerical simulations of heat transport, to calculate the lithospheric-scale conductive thermal field and assess the related geothermal potentials. The contents and structure of the grid files provided here with are described in the Technical Information section.
