这里介绍的 GRIPS 太阳比对项目是“GCM SPARC 现实比对项目 (GRIPS)”的一部分，该项目仅关注 11 年太阳周期变化对大气的影响。当前比较的目的是评估与太阳影响模拟相关的问题，以便更好地定义未来的实验。将呈现不同 GCM 的结果，以调查它们之间或与现有模型研究和观察是否存在一致性。每个不同的 GCM 都使用相同的与波长相关的太阳辐照度变化以及通过二维化学模型计算得出的臭氧变化，从而可以更好地相互比较不同的 GCM。事实证明，每个模型的响应都是不同的，并且模型结果取决于模型气候学，而模型气候学之间以及观测结果之间都有很大差异。
比较过程中遇到的主要问题之一是缺乏太阳对气候影响（例如温度、臭氧）的可靠观测证据。用于模型模拟的强迫（太阳能光谱、臭氧）也存在重要的不确定性。
The GRIPS solar intercomparison project presented here is part of the “GCM Reality Intercomparison Project for SPARC (GRIPS)” focusing only on the influence of 11-year solar-cycle variations on the atmosphere. The aim of the present comparison is to assess the problems related to the simulation of the solar influence in order to better define future experiments. Results from different GCMs will be presented to investigate whether there is any consistency between them or with existing model studies and observations. Each of the different GCMs used the same wavelength-dependent solar irradiance changes as well as the resulting ozone changes calculated with 2-D chemical models enabling a better intercomparison of the different GCMs. It turns out that each model response is different and that the model results are dependent on the model climatologies that vary widely both among themselves and with observations.
One of the major problems encountered during the comparison is the lack of reliable observational evidence for the solar influence on climate (e.g., temperature, ozone). There are also important uncertainties of the forcings used for the model simulations (solar energy spectrum, ozone).
