论文摘要
火星星球吸引的尘埃或全球尘埃雨(GDS)是由当地和区域风暴的综合影响而产生的,这是不常见的大道现象:每3-4我的平均频率大约每3-4我的平均频率,它们在数周到几个月的大气灰尘负载会产生大幅度的增长,从几周到几个月到几个月,并且对大气财产产生了重大影响,并且全球循环,全球循环,全球循环,全球循环。在2018年/MY34全球沙尘暴期间,以L_S = 185 $^\ Circ $(2018年5月30日至31日)发起,MARS Science Laboratory(MSL)Rover进行了一场密集的大气科学运动,以监视Gale Crater的环境参数。我们为以前的独立检索研究做出了贡献,以限制灰尘不透明度并表征气溶胶颗粒特性,包括:大小,形状和单个散射相函数。实施了迭代辐射转移检索程序,以确定最适合MSL导航摄像机(NAVCAMS)在2018/MY34 GDS期间观察到的天空辐射分布的气溶胶参数。
Martian planet-encircling dust storms or global dust storms (GDS), resulting from the combined influence of local and regional storms, are uncommon aperiodic phenomena: with an average frequency of approximately one every 3-4 MY, they produce a substantial rise in the atmospheric dust loading that lasts from weeks to months and have a significant impact on the atmospheric properties, energy budget, and global circulation. During the 2018/MY34 global dust storm, initiated at L_S = 185$^\circ$ (30-31 May 2018), an intensive atmospheric science campaign was carried out by the Mars Science Laboratory (MSL) rover to monitor the environmental parameters at Gale Crater. We contribute to previous studies with independent retrievals to constrain the dust opacity and characterise the aerosol particle properties, including: size, shape and single scattering phase function. An iterative radiative transfer retrieval procedure was implemented to determine the aerosol parameters that best fit the angular distribution of sky radiance at forward and backward scattering regions observed by MSL Navigation Cameras (Navcams) during the 2018/MY34 GDS.
