International Centre for Global Earth Models

The International Centre for Global Earth Models (ICGEM) is a service that collects, archives, and makes available global gravity field models of the Earth to the public in a standardized format. These models include both static and temporal solutions and can be downloaded, visualized interactively, or used within web-based calculation tools to derive gravity field functionals like geoid heights and gravity anomalies.国际全球地球模型中心（International Centre for Global Earth Models，ICGEM）是一家以标准化格式收集、归档并向公众开放地球全球重力场模型的服务机构。此类模型涵盖静态解与时变解两类，支持下载、交互式可视化，也可通过基于网页的计算工具调用，以获取大地水准面高、重力异常等重力场泛函结果。
