Joint Study Group

JSG 3.1: Model representation and geodetic signature of solid-Earth rheology in surface loading problems (joint with IAG Commissions 1 and 2)

Chair: Lambert Caron (Jet Propulsion Lab., California Institute of Technology, Pasadena, USA)

Vice-Chair: Rebekka Steffen (Lantmäteriet, Gävle, Sweden)

Objectives

• Reviewing the established approaches to model surface loading problems, for spectral, grid-based and element-based modeling;
• Assessing the accuracy of and spread between existing modeling frameworks for standardized compressible and transient rheologies;
• Establishing and documenting standard tests and results that enable the community to calibrate current and future efforts to model surface loading problems;
• Encouraging open science and international collaboration for surface loading and geodetic science.
