论文摘要
本文通过处理跨太阳能纵向（LS）42-170的Marci 28和29。Marci可见的数据，在Mars的28和29. MARCI PLACERTAD中，通过处理轨道（LS）42-170的公共可用的原始火星颜色成像器（MARCI）数据来限制在火星的Aphelion Cloud Belt（ACB）中发现的水冰云（WIC）的散射相功能，该数据跨越了太阳能（LS）。云。得出了MARCI蓝色滤清器数据的平均相位函数曲线，并在研究的所有季节中，建模的聚集体，板，实心和空心柱，子弹玫瑰花结和Droxals都被发现都是合理的习惯。发现球是最不合理的，但仍然有可能。此外，这项工作还探究了对立潮，以检查冰水含量和火星上的云不透明度之间线性关系的斜率，并发现对粒子半径有很大的依赖性。发现五个MARCI图像的可见峰值的半宽 - 最大峰值（HWHM）与WIC的建模HWHM更一致，而与灰尘的HWHM相比。
This paper constrains the scattering phase function of water ice clouds (WICs) found within Mars' Aphelion Cloud Belt (ACB), determined from orbit by processing publicly available raw Mars Color Imager (MARCI) data spanning solar longitudes (Ls) 42-170 during Mars Years (MYs) 28 and 29. MARCI visible wavelength data were calibrated and then pipeline-processed to select the pixels most likely to possess clouds. Mean phase function curves for the MARCI blue filter data were derived, and for all seasons investigated, modeled aggregates, plates, solid and hollow columns, bullet rosettes, and droxtals were all found to be plausible habits. Spheres were found to be the least plausible, but still possible. Additionally, this work probed the opposition surge to examine the slope of the linear relationship between column ice water content and cloud opacity on Mars, and found a significant dependence on particle radius. The half-width-half-maxima (HWHM) of the visible 180 degree peak of five MARCI images were found to agree better with modeled HWHM for WICs than with modeled HWHM for dust.
