Data Tables for Water Deposition Rates onto Mars’ South Polar Massive CO2 Ice Deposit (Buhler)

Data Tables for: Buhler, P.B.¹, Water Deposition Rates onto Mars’ South Polar Massive CO2 Ice Deposit. Geophysical Research Journal. <br> ¹Planetary Science Institute; 1700 East Fort Lowell, Suite 106, Tucson, AZ 85719-2395, USA Correspondence e-mail address: [e-mail] Version Date: 2022.09.24 <br> I have provided data tables for figures 2-3 and model routine used in Buhler (2022), GRL. <br> <em><strong>Figure 2</strong></em> <br> Data for plotting Fig 2A. is provided in final_fh2o_array.txt and final_zcap_array, which are both 2-dimensional arrays of height 200 and length 510. final_zcap_array.txt provides vertical demarcations in meters of each ice layer at each of the 510 1-kyr timesteps. final_fh2o_array.txt provides fractional H2O ice content (unitless) of each ice layer at each of the 510 1-kyr timesteps. The obliquity (obl_hist.txt; Fig. 2B), accumulation (accum_histR1.txt for Region 1 and accum_histR2.txt; Fig. 2C), eccentricity (ecc_hist.txt; Fig. 2D), longitude of perihelion (lp_hist.txt; Fig. 2E), and insolation (in_hist.txt; Fig. 2F) histories are provided. Each of these text files is 1-dimensional with length 510 (corresponding to 510 1-kyr timesteps) and has units as stated in their respective subplots. <br> <em><strong>Figure 3</strong></em> <br> The data shown in each panel is presented in each Fig3_panel_#.txt file, where # is a number 0-7 corresponding to the panel letters A-H. Each file is an 8x100 2-dimensional array. Row 1 of 8 provides the orbital parameter, with units and range as shown in each subplot. Rows 2-8 of 8 provide the corresponding 3-, 2-, and 1-sigma low, mean, and 1-, 2-, and 3-sigma high results from each model. <br> <em><strong>Model Routine</strong></em> <br> The stratigraphic model is provided in Buhler_2022_stratigraphic_model.txt.

本数据集包含Buhler(2022)发表于《地球物理研究快报》（GRL）的第2、3幅图及所用模型程序的配套数据表。

**图2**
绘制图2A所需的数据存储于final_fh2o_array.txt与final_zcap_array.txt中，二者均为尺寸200×510的二维数组。其中final_zcap_array.txt记录了510个1千年时间步长下，各冰层的垂直分界（单位：米）；final_fh2o_array.txt则记录了相同时间步长下，各冰层的水冰体积分数（无量纲）。
本数据集同时提供了轨道倾角（obl_hist.txt；对应图2B）、沉积速率（区域1数据为accum_histR1.txt，区域2数据为accum_histR2.txt；对应图2C）、偏心率（ecc_hist.txt；对应图2D）、近日点经度（lp_hist.txt；对应图2E）以及日照量（in_hist.txt；对应图2F）的历史演化数据。上述所有文本文件均为长度510的一维数组（对应510个1千年时间步长），其单位与各子图标注一致。

**图3**
各子图的可视化数据存储于Fig3_panel_#.txt文件中，其中#为0~7的整数，分别对应子图A至H。每个文件均为尺寸8×100的二维数组：第1行记录轨道参数，其单位与取值范围与对应子图标注一致；第2至8行则依次对应各模型的3σ下限、2σ下限、1σ下限、均值以及1σ上限、2σ上限、3σ上限结果。

**模型程序**
层序地层模型存储于Buhler_2022_stratigraphic_model.txt文件中。
