Water vapor on Mars from SPICAM IR occultations (MY27-34)

Dataset for the publication "Multi-annual monitoring of the water vapor vertical distribution on Mars by SPICAM on Mars Express" by Fedorova et al. Includes a list of orbits, and H2O density in cm-3 and H2O mixing ratio in ppm from SPICAM IR/MEX solar occultation observations for 8 Martian years from 27 to 34. Data contain two folders with the list of orbits and H2O density and volume mixing ratio for each orbit. H2O data files are named "orbXXXXXAY_H2O_vmr(density).txt", where XXXXX is the decimal orbit number, Y is the occultation number in orbit.

本数据集配套Fedorova等人发表的题为《利用火星快车（Mars Express）搭载SPICAM仪器开展的火星水汽垂直分布多年监测研究》的学术论文。该数据集涵盖轨道列表，以及来自SPICAM红外/火星快车（SPICAM IR/MEX）太阳掩星观测的、覆盖第27至34个火星年（共8个火星年）的观测数据，其中包含以cm⁻³为单位的水汽密度，以及以ppm（百万分比）为单位的水汽体积混合比。数据集包含两个文件夹，分别存储轨道列表，以及每条轨道对应的水汽密度与体积混合比数据。水汽数据文件的命名格式为"orbXXXXXAY_H2O_vmr(density).txt"，其中XXXXX为十进制轨道编号，Y为该轨道内的掩星观测序号。
