Titan from Many Angles: 3D Mapping of Titan's Methane and Haze Distributions and Surface Spectra

这个项目的目标是使用土卫六上同一表面区域的多个视图来研究它的大气。这将使科学家首次确定土卫六较低大气中甲烷的三维分布。这项工作的更广泛影响包括与地球气候和大气环流模式的潜在相关性，以及本科生参与STEM研究。Keck天文台、哈勃太空望远镜和Amp；VIMS(卡西尼号航天器上的可见光红外成像光谱仪)将拍摄土卫六的图像，以确定低层大气中甲烷和雾霾的三维分布。这项研究将大大加强我们对土卫六上气溶胶的了解，使我们能够搜索大气最低尺度高度上CH4的空间变化，并允许搜索土卫六表面的吸收特征。

The goal of this program is to use multiple views of the same surface area on Titan to study its atmosphere. It will allow scientists to determine the three dimensional distribution of methane in Titan's lower atmopshere for the first time. Broader impacts of the work include potential relevance to climate and atmospheric circulation patterns on Earth, and involvement of undergraduates in STEM research.Titan will be imaged by the Keck Observatory, the Hubble Space Telescope, & VIMS (Visible-Infrared Imaging Spectrometer, an instrument on the Cassini spacecraft) to determine the 3-D distribution of methane and hazes in the lower atmosphere. This research will significantly enhance our understanding of aerosols on Titan, enable the search for spatial variation in CH4 in the lowest scale height of the atmosphere, and permit the search for absorption features on Titan's surface.
