抽象的。模块化地球子模型系统（MESSy）提供了一个接口，通过高度灵活的数据管理设施将子模型耦合到基本模型（Jockel 等，2010）。在本文中，我们提出了四个新的辐射相关子模型 RAD、AEROPT、CLOUDOPT 和 ORBIT。子模型RAD（包括短波辐射方案RAD_FUBRAD）模拟辐射传输，子模型AEROPT计算气溶胶光学特性，子模型CLOUDOPT计算云光学特性，子模型ORBIT负责地球轨道计算。这些子模型通过标准 MESSy 基础设施耦合，很大程度上基于大气环流模型 ECHAM5 的原始辐射方案，但通过附加功能进行了扩展。这些功能包括用户友好且灵活可控（通过名单）的在线辐射强迫计算（通过辐射例程的多个诊断调用）。这样，现在就可以在一次模拟中同时计算各种温室气体的辐射强迫（瞬时和平流层调整）以及云扰动的辐射强迫。介绍了 ECHAM/MESSy 大气化学 (EMAC) 模型中在线辐射强迫计算的示例。
Abstract. The Modular Earth Submodel System (MESSy) provides an interface to couple submodels to a base model via a highly flexible data management facility (Jockel et al., 2010). In the present paper we present the four new radiation related submodels RAD, AEROPT, CLOUDOPT, and ORBIT. The submodel RAD (including the shortwave radiation scheme RAD_FUBRAD) simulates the radiative transfer, the submodel AEROPT calculates the aerosol optical properties, the submodel CLOUDOPT calculates the cloud optical properties, and the submodel ORBIT is responsible for Earth orbit calculations. These submodels are coupled via the standard MESSy infrastructure and are largely based on the original radiation scheme of the general circulation model ECHAM5, however, expanded with additional features. These features comprise, among others, user-friendly and flexibly controllable (by namelists) online radiative forcing calculations by multiple diagnostic calls of the radiation routines. With this, it is now possible to calculate radiative forcing (instantaneous as well as stratosphere adjusted) of various greenhouse gases simultaneously in only one simulation, as well as the radiative forcing of cloud perturbations. Examples of online radiative forcing calculations in the ECHAM/MESSy Atmospheric Chemistry (EMAC) model are presented.
