Gravity forward modelling benchmark dataset

This document describes the different benchmark codes to reproduce the figures from the SolidEarth article:<br>Root, B. and Sebera, J. and Szwillus, W. and Thieulot, C. and Martinec, Z. and Fullea, J., Benchmark forward gravity schemes: the gravity field of a realistic lithosphere model WINTERC-G, Solid Earth Discussions, 2021, 1--36, 10.5194/se-2021-145.<br>Three different benchmarks are discussed:<br>- shell test 2 - Equal thickness lateral varying density- shell test 3 - Lateral varying density interface (CRUST1.0 MOHO)- WINTERC-grav benchmark full layered model<br>The Matlab codes and data files are presented in the database.
