论文摘要
本文描述了系外行星观测的可居住能量平衡模型（HEXTOR），该模型是计算地球和其他快速旋转行星上纬度温度谱的模型。 Hextor包括一种查找表方法，用于计算传出红外辐射通量和行星反照率，该方法在能量平衡模型中的参数化辐射传递方面提供了比其他方法的改进。为当今的地球和其他地球大小的行星提出了验证案例，其水膜和陆地行星条件从0到45度。能量平衡模型还实现了潮汐锁定的坐标系，该模型可以计算行星在低质量恒星周围同步旋转中的水平温度剖面。该坐标转换的模型适用于Trappist宜居氛围对比协议所定义的Trappist-1E病例，与纬度能量平衡模型相比，该模型证明了与一般循环模型更好的一致性。可以通过使用通用循环模型作为调整的基准以及通过不同物理参数化的能量平衡模型之间进行相互作用来实现将能量平衡模型应用于系外行星的进步。
This paper describes the Habitable Energy balance model for eXoplaneT ObseRvations (HEXTOR), which is a model for calculating latitudinal temperature profiles on Earth and other rapidly rotating planets. HEXTOR includes a lookup table method for calculating the outgoing infrared radiative flux and planetary albedo, which provides improvements over other approaches at parameterizing radiative transfer in an energy balance model. Validation cases are presented for present-day Earth and other Earth-sized planets with aquaplanet and land planet conditions from 0 to 45 degrees obliquity. A tidally locked coordinate system is also implemented in the energy balance model, which enables calculation of the horizontal temperature profile for planets in synchronous rotation around low mass stars. This coordinate transformed model is applied to cases for TRAPPIST-1e as defined by the TRAPPIST Habitable Atmosphere Intercomparison protocol, which demonstrates better agreement with general circulation models compared to the latitudinal energy balance model. Advances in applying energy balance models to exoplanets can be made by using general circulation models as a benchmark for tuning as well as by conducting intercomparisions between energy balance models with different physical parameterizations.
