Abstract

Abstract. An extensive sensitivity analysis was performed for a horizontally homogeneous and hydrostatic 1-D column model at the Mars Science Laboratory (MSL) location. Model experiments were compared with observations from the Curiosity Rover Environmental Monitoring Station humidity (REMS-H) device and ChemCam. Based on our earlier column model investigations, model surface temperature and pressure, dust optical depth (τ), and column precipitable water content (PWC) were the parameters that we investigated with our sensitivity analysis. Our analysis suggests that the most sensitive parameters for the column model temperature profile are τ and surface temperature. The initial value of PWC does not affect the temperature profile of the model, but it is the most important parameter for the humidity profile. The fixed value of τ also seems to have some effect on the humidity profile of the model. Based on our analysis, variations in surface pressure initialization are negligible for the model's temperature and almost negligible for the model's humidity predictions. The model simulations are generally in good agreement with the observations. Our additional model experiments with a different shape of the model's initial humidity profile yielded better results compared to the well-mixed assumption in the predicted water vapor volume mixing ratios at 1.6 m.
利用火星科学实验室的数据对火星大气柱模型进行灵敏度分析
摘要。对火星科学实验室(MSL)位置的水平均质和静水一维柱模型进行了广泛的敏感性分析。模型实验与好奇号漫游车环境监测站湿度(REMS-H)装置和化学摄像机的观测结果进行了比较。根据我们早期的气柱模型调查,模型表面温度和压力、尘埃光学深度 (τ) 和气柱可降水含量 (PWC) 是我们通过敏感性分析进行调查的参数。我们的分析表明,对气柱模式温度曲线最敏感的参数是 τ 和表面温度。PWC 的初始值不会影响模型的温度曲线,但却是湿度曲线的最重要参数。τ 的固定值似乎也对模型的湿度曲线有一定影响。根据我们的分析,表面压力初始化的变化对模型温度的影响可以忽略不计,而对模型湿度预测的影响几乎可以忽略不计。模型模拟结果与观测结果基本吻合。与 1.6 米处水汽体积混合比预测的混合良好假定相比,我们对模型初始湿度曲线的不同形状进行了额外的试验,结果更好。

期刊介绍: Annales Geophysicae (ANGEO) is a not-for-profit international multi- and inter-disciplinary scientific open-access journal in the field of solar–terrestrial and planetary sciences. ANGEO publishes original articles and short communications (letters) on research of the Sun–Earth system, including the science of space weather, solar–terrestrial plasma physics, the Earth''s ionosphere and atmosphere, the magnetosphere, and the study of planets and planetary systems, the interaction between the different spheres of a planet, and the interaction across the planetary system. Topics range from space weathering, planetary magnetic field, and planetary interior and surface dynamics to the formation and evolution of planetary systems.
