论文摘要
随着已知的系外行星的数量已经攀升到成千上万,理论家努力了解可居住区域中陆地行星上可能存在的气候多样性也加速了。这些努力从分析到简单的0-D,1-D和2-D模型,再到来自地球气候和天气模型的高度熟悉的3D全球气候模型(GCM)。后者的优点是,更少的物理过程将减少为简单的参数化和经验拟合,而可以通过物理动机的算法来表示。但是,许多这样的模型很难使用,并且相对于更简单的模型,需要很长时间才能达到收敛状态,从而限制了可以探索的参数空间的数量。我们使用Plasim(中间复杂性的3D气候模型)来弥合这一间隙,从而使我们能够产生数百至数千个模型输出,这些模型输出已经达到了大气表面和顶部的能量平衡平衡。我们正在以永久性存储库(https://dataverse.scholarsportal.info/dataverse/kmenou)提供模型输出。我们的模型输出子集可以直接与外部光谱后处理工具一起使用,并且我们已将它们与Petitradtrans和SBDART一起使用,以创建代表完全3D气候的合成可观测值。该存储库的另一个自然用途是使用更熟悉的GCM跨检查和验证Plasim的结果,并更详细地探索我们在我们的等离子结果中鉴定出的外部参数空间的那些区域。将来,我们将继续为该存储库添加模型,其中包括短期至中期未来的1000多个模型,从而扩大了其中代表的气候的多样性。
As the number of known exoplanets has climbed into the thousands, efforts by theorists to understand the diversity of climates that may exist on terrestrial planets in the habitable zone have also accelerated. These efforts have ranged from analytical, to simple 0-D, 1-D, and 2-D models, to highly-sophisticated 3D global climate models (GCMs) adapted from Earth climate and weather models. The advantage of the latter is that fewer physical processes are reduced to simple parameterizations and empirical fits, and may instead be represented by physically-motivated algorithms. However, many such models are difficult to use, and take a long time to reach a converged state relative to simpler models, thereby limiting the amount of parameter space that can be explored. We use PlaSim, a 3D climate model of intermediate complexity, to bridge this gap, allowing us to produce hundreds to thousands of model outputs that have reached energy balance equilibrium at the surface and top of the atmosphere. We are making our model outputs available to the community in a permanent Dataverse repository (https://dataverse.scholarsportal.info/dataverse/kmenou). A subset of our model outputs can be used directly with external spectral postprocessing tools, and we have used them with petitRADTRANS and SBDART in order to create synthetic observables representative of fully-3D climates. Another natural use of this repository will be to use more-sophisticated GCMs to cross-check and verify PlaSim's results, and to explore in more detail those regions of the exoplanet parameter space identified in our PlaSim results as being of particular interest. We will continue to add models to this repository in the future, including more than 1000 models in the short- to medium-term future, expanding the diversity of climates represented therein.
