我们描述了使用ISCA对太阳系行星进行分层建模，并特别关注地球、火星和木星。ISCA是一个建模框架，用于构建和使用不同复杂程度的行星大气模型，从通过热松弛迫使大气回到指定温度的无特征的行星模型，到没有大陆(或海洋)的简单辐射方案的水行星，到具有多波段辐射方案、对流方案和可配置的大陆和地形的近乎全面的模型。通过明智地选择参数和参数化方案，该模型可以针对相当任意的行星进行配置，恒星辐射输入由天文参数确定，并考虑到行星的倾角和偏心率。在这篇文章中，我们描述了使用原始方程和/或浅水方程建立和使用不同复杂程度的地球、火星和木星的模型。
We describe the use of Isca for the hierarchical modeling of Solar System planets, with particular attention paid to Earth, Mars, and Jupiter. Isca is a modeling framework for the construction and use of models of planetary atmospheres at varying degrees of complexity, from featureless model planets with an atmosphere forced by a thermal relaxation back to a specified temperature, through aquaplanets with no continents (or no ocean) with a simple radiation scheme, to near-comprehensive models with a multi-band radiation scheme, a convection scheme, and configurable continents and topography. By a judicious choice of parameters and parameterization schemes, the model may be configured for fairly arbitrary planets, with stellar radiation input determined by astronomical parameters, taking into account the planet’s obliquity and eccentricity. In this paper, we describe the construction and use of models at varying levels of complexity for Earth, Mars and Jupiter using the primitive equations and/or the shallow water equations.
