Water and dust in the Mars atmosphere from the Rosalind Franklin rover

伦敦大学学院领导的PanCam仪器（科茨等人，欧空局-俄罗斯罗莎琳德富兰克林火星车计划于2020年发射，预计将于2021年抵达火星。PanCam仪器由两个广角摄像机（WAC）组成，每个摄像机都包括一个11位滤光轮，并配有一个高分辨率摄像机。在使命期间，来自WAC的不同波长的图像将提供地质和大气背景。在这个项目中，学生将专注于PanCam的大气科学目标：水蒸气，灰尘含量和可变现象。在火星接近日落时，PanCam将利用93. 6纳米水吸收特征附近的滤光片来确定沿着视线的大气含水量。学生将开发模型，将这些数据转化为高度剖面，并类似地研究灰尘含量和沙尘暴。还将有一个实验方面，使用有代表性的硬件来测量地球上的大气影响。

The UCL-led PanCam instrument (Coates et al., 2017) on the ESA-Russia Rosalind Franklin rover is due to reach Mars in 2021 following its planned launch in 2020. The PanCam instrument consists of two wide angle cameras (WACs), each of which include an 11-position filter wheel, complemented by a high-resolution camera. Images from the WACs at different wavelengths will provide geological and atmospheric context during the mission. In this project the student will concentrate on the atmospheric science goals of PanCam: water vapour, dust content and variable phenomena. Near sunset on Mars, PanCam will use filters near the 93.6 nm water absorption feature to determine the atmospheric water content along the line of sight. The student will develop models to invert these data into a height profile, and similarly study dust content and dust devils. There will also be an experimental aspect using representative hardware to measure atmospheric effects on Earth.
