This archive contains supplemental data for the manuscript Wieczorek, M. A., et al., InSight constraints on the global character of the Martian crust, Journal of Geophysical Research: Planets, 2022. ARCHIVE CONTENTS constant-density-summary.xlsx Summary of all constant-density crustal thickness models. Each sheet provides model results that fit a specified crustal thickness at the InSight landing site. Summarized parameters include: the name of the interior model for the mantle and core, the density of the crust, the density of the upper mantle, the predicted crustal thickness beneath the InSight landing site, the average crustal thickness of the model, the minimum thickness of the model, the maximum thickness of the model, the average crustal thickness south of the dichotomy boundary, the average crustal thickness north of the dichotomy boundary, the average crustal thickness in the Tharsis province, the average crustal thickness south of the dichotomy boundary (excluding the Tharsis province), and the average crustal thickness north of the dichotomy boundary (excluding the Tharsis province). The first sheet summarizes a few of the main characteristics of the models. dichotomy-summary.xlsx Same as for constant-density-summary.xlsx, but for the models that consider different densities north and south of the dichotomy boundary. make-grids.py A python script that reads the spherical harmonic coefficients in the directories "constant" and "dichotomy" and creates grids of the planetary shape, the crust-mantle interface, and the crustal thickness. This script makes use of the file "dichotomy_coordinates-JAH-0-360.txt", which is a list of (longitude, latitude) coordinates of the dichotomy boundary from Andrews-Hanna et al. (2008). constant/ Spherical harmonic coefficients of the shape of the crust-mantle interface. The file names are of the format "Moho-Mars-MODEL-THICK-RHO.sh", where MODEL is the assumed interior model used for the mantle and core, THICK is the assumed seismic thickness at the InSight landing site, and RHO is the density of the crust. dichotomy/ Spherical harmonic coefficients of the shape of the crust-mantle interface. The file names are of the format "Moho-Mars-MODEL-THICK-RHOS-RHON.sh", where RHOS and RHON are respectively the densities south and north of the dichotomy boundary. When RHOS and RHON are equal, the model corresponds to the constant density model in the directory "constant" (note that the numerical values are not identical as a result of using two different numerical approaches). grids/ Gridded output files generated by the script "make-grids.py" are placed in this directory. The file names are of the format "Mars-KIND-MODEL-THICK-RHOS-RHON", where KIND is either "shape" for the radius of the surface, "moho" for the radius of the crust-mantle interface, or "thick" for the crustal thickness. Filenames with the extension "dat" are in an ascii raster format with the first and last data points (in units of km) corresponding to (90 N, 0 E) and (90 S, 360 E), respectively. Filenames with the extension "xyz" are lists of (latitude, longitude, value, density), where latitude and longitude are in degrees, value is in km, and density is in kg/m3. The grids directory contains the precomputed data used to create Figures 2 and 5 in the manuscript. For these files, the grid spacing in both latitude and longitude is 0.25 degrees. For the ascii raster files, the number of lines (latitudes) is 721, and the number of elements (longitudes) in each line is 1441.
