The era of atmospheric characterization of terrestrial exoplanets is just around the corner. Modeling prior to observations is crucial in order to predict the observational challenges and to prepare for the data interpretation. This paper presents the report of the TRAPPIST Habitable Atmosphere Intercomparison workshop (2020 September 14–16). A review of the climate models and parameterizations of the atmospheric processes on terrestrial exoplanets, model advancements, and limitations, as well as direction for future model development, was discussed. We hope that this report will be used as a roadmap for future numerical simulations of exoplanet atmospheres and maintaining strong connections to the astronomical community.

对类地系外行星进行大气表征的时代即将到来。在观测之前建模对于预测观测挑战和为数据解释做准备至关重要。本文介绍了 TRAPPIST 可居住大气比对研讨会（2020 年 9 月 14-16 日）的报告。讨论了地球系外行星大气过程的气候模型和参数化、模型进步和局限性以及未来模型开发的方向。我们希望这份报告将被用作未来系外行星大气数值模拟的路线图，并与天文学界保持密切联系。
