During the last years fundamental scientific investigations have been carried out to understand the interactions within the ¿system Earth¿ and their effects on the Earth rotation parameters. New scientific insights in the fields of the dynamics of the Earth¿s interior and the magnetic field, the angular momentums of the new ocean, atmospheric and hydrological models are often recognized as basic findings. The integration of new results in an overall ¿system Earth¿ to broaden the understanding is limited by the factor of insufficient interoperability. ERIS will organize a software package to describe and visualize the rotation of the ¿system Earth¿ based on the state of the art models, partly developed within this research program. An open standard for the interoperability between software packages allows the combination of the various models describing the single components affecting the Earth rotation. In the future this standard facilitates the integration of more recent developments or models. The envisaged software package ERIS will serve as a powerful scientific instrument. The various scientific models for the system Earth and its interactions including relevant equations of motions (such as the Euler-Liouville equation) and excitation functions will be available on a modular basis. The user will be able to switch on and off the various interactions and learn directly the results on the EOP. In that way the effect of also weak forces in the Earth¿s system can be understood and small signals in the data be interpreted. The knowledge based system ERIS will guide experts as well as interested non professional users by applying user-adapted interfaces and will be the interface for all projects involved in this research proposal as central Information, Communication and Database System.

在过去几年中，进行了基础科学调查，以了解地球系统内的相互作用及其对地球自转参数的影响。在地球内部动力学和磁场、新海洋角动量、大气和水文模型等领域的新科学见解往往被视为基本发现。将新的成果纳入一个整体系统以扩大理解受到互操作性不足的限制。ERIS将组织一个软件包，以描述和可视化的基础上的最先进的模型，部分开发在这个研究计划的“系统地球”的旋转。软件包之间互操作性的开放标准允许将描述影响地球自转的单个组件的各种模型组合起来。在未来，该标准有助于整合更新的开发或模型。设想中的ERIS软件包将成为一种强有力的科学工具。地球系统及其相互作用的各种科学模型，包括有关的运动方程（如欧拉-刘维尔方程）和激发函数，将以模块形式提供。用户将能够打开和关闭各种交互，并直接了解EOP上的结果。通过这种方式，可以理解地球系统中同样微弱的力的影响，并解释数据中的小信号。基于知识的系统ERIS将指导专家以及感兴趣的非专业用户通过应用用户自适应的界面，并将在本研究提案中涉及的所有项目的接口作为中央信息，通信和数据库系统。
