我们描述了目前的状态，大气太赫兹辐射分析和模拟（AMATERASU），正在开发的NICT太赫兹项目的框架。该代码旨在研究太赫兹频段的大气遥感、通信系统以及估算太赫兹热大气辐射对地球能量收支的影响。本文介绍了模式发展的第一阶段，涉及一个非散射和水平均匀的大气，例如，地球物理参数仅取决于高度。一个散射模块正在开发中，但它是在其他文件在这个问题上。该模型是基于微波观测和线路估计和检索代码（MOLIERE）。为了将频率覆盖范围从亚毫米波长扩展到近红外区，对吸收系数模块进行了修改。一种新的辐射传输模块已经实现，可以处理不同类型的光路和任何位置的接收器。AMATERASU包括原始MOLIERE仪器模拟器和检索代码。的验证方法进行了讨论，并给出了当前的应用程序的一些例子。在结论中提出了下一步的发展，包括在大气中的水平不均匀性的建模。
We describe the current status of the Advanced Model for Atmospheric TeraHertz Radiation Analysis and Simulation (AMATERASU) that is being developed in the framework of the NICT THz project. This code aims to be used for studying the insterest of the THz frequency region for atmospheric remote sensing, communication systems and estimate the impact of the THz thermal atmospheric emission in the Earth energy budget. This paper presents the first stage of the model development that concerns a non scattering and a horizontal homogeneous atmosphere, e.g., the geophysical parameters are only altitude dependent. A scattering module is being developed but it is presented in an other paper in this issue. The model is based on the Microwave Observation and Lines Estimation and REtrieval code (MOLIERE). The absorption coefficient module has been modified in order to extend the frequency coverage from the submillimeter wavelength to the near InfraRed region. A new radiative transfer module has been implemented that can handle the different types of optical paths and any location for the receiver. AMATERASU includes the original MOLIERE instrument simulator and retrieval codes. The validation methodology is discussed and some examples of the current applications are given. The next steps of the development are presented in the conclusion including the modeling of the horizontal inhomogeneties in the atmopshere.
