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.

本文档详述了可复现《Solid Earth》期刊论文中各类图表的基准测试代码：作者为Root, B.、Sebera, J.、Szwillus, W.、Thieulot, C.、Martinec, Z.与Fullea, J.，论文题为《正向重力模拟基准测试：真实岩石圈模型WINTERC-G的重力场》，发表于《Solid Earth Discussions》，2021年，页码1--36，DOI为10.5194/se-2021-145。
本文共讨论三类基准测试：
- 壳层测试2：等厚度横向密度变化模型
- 壳层测试3：横向密度界面（CRUST1.0莫霍界面（MOHO））
- WINTERC-grav基准测试全分层模型
相关Matlab代码与数据文件已收录于数据库中。
