High-resolution gravity maps of the Earth, Moon and Mars

Provided is a collection of gravity maps of the Earth, Moon and Mars developed by Christian Hirt et al. Most of the models rely on gravity-forward modelling of topographic masses, reaching resolutions as high as 3 arcsec (SRTM2gravity). The maps can be used, for instance, to significantly improve the accuracy and resolution of global spherical harmonic gravity models such as EGM2008. Some of the models, (e.g., GGMplus) already contain the global long-wavelength information from spherical harmonic models, so can be used on their own. For each model, attached are manuscripts with detailed information on the development and the use of the models as well as on their authors.

本数据集汇集了由Christian Hirt等研究者开发的地球、月球和火星的重力场图。其中大部分模型依赖于地形质量的重力正向建模，分辨率高达3角秒（SRTM2gravity）。这些地图可用于显著提升诸如EGM2008等全球球谐重力模型的准确性和分辨率。部分模型（如GGMplus）已包含来自球谐模型的全局长波信息，因此可独立使用。对于每个模型，均附有关于模型开发与使用以及作者详细信息的论文。
