Regional variations of Mercury's crustal density and porosity from MESSENGER gravity data

DescriptionThis dataset archives the gravity field solution HgM009 and the results of 230 admittance analyses used to construct maps of Mercury’s crustal density, porosity, and lithospheric structure. The materials support the study “Regional variations of Mercury's crustal density and porosity from MESSENGER gravity data”. The dataset is organized into the following folders: HgM009: Gravity solution and full covariance matrix. The covariance matrix includes terms in the order: C20, C21, C21, C30, …, C160160, S21, S22, S31, S32, …, S160160. Maps: Gridded files of lateral variations in crustal density, crustal thickness, porosity, and elastic thickness of the lithosphere. AdmittanceSpectra: Figures showing correlation and admittance spectra. Misfit&Histograms: Misfit plots and histograms of estimated parameters from top-load modeling in the admittance analyses. LocalizationResults: Summary files with information on the localization windows adopted in each analysis and the corresponding parameter estimates. CitationPlease cite as:Genova, A., et al. (2022).
