Greenland Earth structure and GIA models datasets

This folder contains several models introduced in the following paper: "Upper mantle temperatures illuminate Iceland hotspot track and understanding of ice-earth interactions in Greenland" Authors: Parviz Ajourlou, Glenn A. Milne, Ryan Love, Juan C. Afonso, Farshad Salajegheh, Konstantin Latychev, Kristian K. Kjeldsen, Alexis Lepipas, Yasmina M. Martos, and Sarah Woodroffe Introduced models are divided into three separate folders: litmod, RSL, and VLM. The LitMod inversion yields many earth structure realizations, and we provide those we used in this paper and are most confident in. In the litmod folder, there are files provided: + GFdata1: First geophysical data set + Format: Longitude, Latitude, depth, density, 1-sigma, Vp, 1-sigma, Vs, 1-sigma + GFdata2: Second geophysical data set + Format: Longitude, Latitude, SHF, 1-sigma, Geoid, 1-sigma, Topography, 1-sigma, LAB, 1-sigma * In GFdata2, except for LAB, the other models are the revised input data model from previous studies. + Temp: Longitude, Latitude, Depth, Temperature, 1-sigma * Note that the plots in the paper are interpolated to a finer grid and smoothed The VLM folder contains VLM rates as follows: + VLM_sites: 3D and 1D VLM rates with uncertainty at GNET sites + Format: Site, Longitude, Latitude, Mean-3D, 1-Sigma, Mean-1D, 1-Sigma * Note 3D and 1D VLM rates are the sum of deglacial (DG), Little Ice Age (LIA), and Peripheral Glaciers (PG) components + VLM_grid_3D: Spatial 3D VLM rates with uncertainty + Format: Longitude, Latitude, Mean-3D-DG, 1-sigma, Range, Low-LIA, High-LIA, PG * Note range is the amount of VLM rates spread of the 50-ensemble models. The RSL folder contains RSL as follows: + RSL_1D: RSL with the best 1D (radial) earth model at paleo RSL sites since 21 ka to the present. +Format: Sites 1D-RSL (at different times) + RSL_3D_mean: The mean 50 ensemble 3D RSL models at paleo RSL sites since 21 ka to the present. +Format: Sites Mean-3D-RSL (at different times) + RSL_3D_1sig: The 1-sigma uncertainty of 50 ensemble 3D RSL models at paleo RSL sites since 21 ka to the present. +Format: Sites 1-sigma uncertainty (at different times) + RSL_3D_range: The range of 50 ensemble 3D RSL models at paleo RSL sites since 21 ka to the present. +Format: Sites Range (at different times) + RSL_grid_8kyrBP: Spatial 3D RSL with uncertainty +Format: Longitude, Latitude, RSL, 1-sigma, range Data DOI: 10.5281/zenodo.16584413
