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.

UCL领导的PanCam仪器(Coates等人，2017)安装在欧空局-俄罗斯Rosalind Franklin月球车上，计划于2020年发射，2021年到达火星。PanCam仪器由两个广角相机(WAC)组成，每个相机都包括一个11位滤光轮，并由一个高分辨率相机补充。来自WAC的不同波长的图像将在任务期间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、尘埃含量和变化现象。在火星上接近日落时，PanCam将使用93.6 nm水吸收功能附近的滤光片来确定视线沿线的大气水分含量。这名学生将建立模型，将这些数据转化为身高分布，并类似地研究尘埃含量和尘暴。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。
