Abstract
In Finger et al. (2020), we created consistent three dimensional models in terms of temperature, density and composition of the upper mantle of the cratonic South American Platform ("Upper MAntle Model") by combining seismic (Celli et al., 2020, Schaeffer amp; Lebedev, 2013) and gravity (Förste et al., 2014) data with mineral physics constraints in an iterative integrated inversion approach (Kaban et al., 2014; Tesauro et al., 2014). We further compiled a new crustal model ("Crustal Model"), including sediment and average crustal density and depth to the Moho to correct the gravity field for crustal effects and calculate the residual topography. To obtain these models we used data from the GSC (Global Seismic Catalog, Mooney, 2015 with updates up to 2019). To calculate depth to the Moho, the GSC data were combined with those published by Rivadeneyra-Vera et al. (2019). Here, we share the initial and final models of the upper mantle, sediment density and crust that are discussed in the article as well as the test cases set up in the uncertainty assessment. The upper mantle models are given in six layers centered at 50, 100, 150, 200, 250 and 300 km. All models range from -60.5°N to 15.5°N and -90.5°E to -29.5°E, except for the sediment density model (-59.5°N to 24.5°N and -99.5°E to -25.5°E) with a 1° by 1° lateral resolution. A detailed description of the respective files is given in each subfolder. All data are in ASCII format.
