Spectral data used in the paper "Intense Zonal Wind in the Martian Mesosphere During the 2018 Planet Encircling Dust Event Observed by Ground-based IR Heterodyne Spectroscopy"

-------------------<br> GENERAL INFORMATION<br> ------------------- 1. Title of Dataset: <br> MILAHI 2018PEDE Spectral Data 2. Authors:<br> Akiho Miyamoto, [e-mail] 3. Contact information:<br> Akiho Miyamoto, [e-mail]<br> Hiromu Nakagawa, [e-mail] 4. Observation dates:<br> June 21 2018, June 27 2018, and August 31 2018 ----------------------<br> FOLDER &amp; FILE OVERVIEW<br> ---------------------- There are three data files for 21_June_2018, 27_June_2018、 and 31_August_2018, respectively in MILAHI_2018PEDE_Spectrum_Data. "MILAHI_2018PEDE_integrated_spectral_data" includes (1) the integrated spectral data for Figure 2, and (2) the individual spectral data for Figures S1, S3, S5. (1) The integrated spectral data in Figure 2:<br> The first column is the intermediate frequency, the second column and third column are the relative intensity of the disk center, and the equatorial limb, respectively. The intermediate frequency of the spectra at the equatorial limb is corrected after taking into account the Doppler shift due to the solid rotation of Mars body. (2) The individual spectral data in Figures S1, S3, S5:<br> "disk_center" folder includes the individual spectrum observed at the Martian disk center showed in Figures S1, S3, S5 in Supporting Information. "equatorial_limb" folder is the same as the "disk center", except for the data at the observed position to the equatorial limb. The first column is the intermediate frequency and the second column is the relative intensity.<br> Note, for the equatorial limb data, the data are also corrected for the Martian solid rotation, while the spectra shown in Figs S1, S3, S5 are not. <br> --------------------<br> MEANIG OF DATA NAMES<br> -------------------- The file name of the individual spectrum includes the date and time(UT), relative velocity between Earth and Mars, the CO2 gas laser wavelength, and the observed position.<br> "vd" is the relative velocity and "lambda" is the CO2 gas laser wavelength (e.g., 1051 corresponds 10.51 micron). Thus, for example, the data name "20180621T1130_vd-8.86_lambda1059_disk_center" means that the date is 21 June 2018, time is 11:30 UT, relative velocity is -8.86 km s-1, and the CO2 gas laser wavelength is 10.59 micron. <br> -------------------<br> POINT OF ATTENTION<br> ------------------- The spectra in MILAHI observation at the summit of Mt. Haleakala, HI, were taken both on and off Mars using two beam paths. The individual spectrum is the result of minimizing systematic features using the two beam path data with close observation time. The data in this archive are relevant for the revised manuscript.一、数据集基本信息 1. 数据集名称：MILAHI 2018PEDE光谱数据 2. 作者：Akiho Miyamoto，联系邮箱：[e-mail] 3. 联系方式：Akiho Miyamoto（邮箱同上）、Hiromu Nakagawa，联系邮箱：[e-mail] 4. 观测日期：2018年6月21日、2018年6月27日及2018年8月31日 二、文件夹与文件概览 在MILAHI_2018PEDE_Spectrum_Data数据集包中，分别包含对应2018年6月21日、2018年6月27日与2018年8月31日的3组数据文件。"MILAHI_2018PEDE_integrated_spectral_data"包含两类数据：(1) 用于绘制图2的整合光谱数据，以及(2) 用于补充材料图S1、S3、S5的单条光谱数据。 (1) 图2的整合光谱数据：第一列为中频，第二列与第三列分别为火星盘心与赤道边缘的相对强度。考虑到火星本体固体自转产生的多普勒频移后，已对赤道边缘光谱的中频进行了校正。 (2) 补充材料图S1、S3、S5的单条光谱数据："disk_center"（盘心）文件夹包含观测于火星盘心的单条光谱，对应补充材料中的图S1、S3、S5；"equatorial_limb"（赤道边缘）文件夹的内容与盘心文件夹一致，仅观测位置为火星赤道边缘。该类数据的第一列为中频，第二列为相对强度。 注意：赤道边缘的数据已针对火星固体自转完成校正，而图S1、S3、S5中的光谱未进行此项校正。 三、数据命名规则 单条光谱的文件名包含观测日期与时间（世界时UT）、地球与火星间的相对速度、CO₂气体激光波长以及观测位置。其中"vd"代表相对速度，"lambda"代表CO₂气体激光波长（例如1051对应10.51微米）。例如，文件名"20180621T1130_vd-8.86_lambda1059_disk_center"表示：该数据的观测日期为2018年6月21日，观测时间为世界时11:30，相对速度为-8.86 km·s⁻¹，CO₂气体激光波长为10.59微米。 四、注意事项 在夏威夷州哈雷阿卡拉火山山顶开展的MILAHI观测中，采用双光路分别对火星及天区背景进行了观测。单条光谱是通过使用观测时间相近的双光路数据，以最小化系统误差得到的结果。本存档中的数据对应修订后的稿件。
