Surface Deformations from Glacial Isostatic Adjustment Models with Laterally Homogeneous, Compressible Earth Structure Omitting the Greenland Ice Sheet Load

The zipped file contains global 1-degree grid files of four different surface deformation parameters: Horizontal velocity, North component (vnorth), in mm/a Horizontal velocity, East component (veast), in mm/a Vertical velocity (vup), in mm/a Geoid change (dgeoid), in mm/a calculated with the software ICEAGE (Kaufmann, 2004) from a set of 26 different glacial isostatic adjustment models applying 10 different radially varying (=layered) earth structures and 3 different global ice models where the Greenland ice sheet is omitted. The content is thus similar to Steffen (2021), but for the deformation calculation the Greenland ice sheet was removed from each ice history. The different earth structures and the available combinations with ice models can be found in the readme.pdf. File naming is simply {ice model}_{earth model}_{parameter}.grd. For example, anu-ice_ng_f72_vup.grd is the global vertical velocity grid file (vup.grd) calculated with a GIA model with ANU-ICE ice history (anu-ice) without Greenland ice sheet (ng) and 60 km lithospheric thickness, 4E20 Pa s upper mantle viscosity and 2E21 Pa s lower mantle viscosity (f72). Grid files (NetCDF format) were generated with GMT6 (Wessel et al., 2019), thus can be directly used. For more information on the calculation method, see Steffen (2021).
