Measuring Aeolian Saltation Flux Profiles: Comparison of Methods

Overview: The file (“DataFluxProfile.csv”) includes vertical flux profiles of sand mass captured by arrays of 9-mesh sand traps, following the method of Sherman et al. (2014). These data were collected from three field sites in Jericoacoara, Ceará, Brazil, during October 2022. The continuous profiles, obtained from vertically stacked arrays of nine sand traps, are used to test potential errors that arise when using discontinuous arrays of devices such as BSNE and MWAC traps or alternative devices like the Wenglor fork laser particle counter. The evaluation is based on the nine index heights of our continuous profile (https://doi.org/10.5281/zenodo.15700463). For more information about the experimental setup and data analysis, please refer to the accompanying paper: “Measuring Aeolian Saltation Flux Profiles: Comparison of Methods.” Key to variables: Site: Specific field site in Jericoacoara, Ceará, Brazil (refer to Figures 1 and 2 in the paper). Date Collection (mm/dd/yyyy): Date of data collection. Time Duration (second): Duration of each flux profile measurement run. Median Grain Size (micrometer): Median diameter of collected sand grains. Trap 1 (gram): Sand mass collected from the surface to 25 mm height. Trap 2 (gram): Sand mass collected from 25 to 50 mm height. Trap 3 (gram): Sand mass collected from 50 to 75 mm height. Trap 4 (gram): Sand mass collected from 75 to 100 mm height. Trap 5 (gram): Sand mass collected from 100 to 150 mm height. Trap 6 (gram): Sand mass collected from 150 to 200 mm height. Trap 7 (gram): Sand mass collected from 200 to 250 mm height. Trap 8 (gram): Sand mass collected from 250 to 350 mm height. Trap 9 (gram): Sand mass collected from 350 to 450 mm height. Total Mass (gram): Total sand mass collected from the surface to 450 mm height. The file “FluxProfileCombinationTest.m” (10.5281/zenodo.15700463) is a MATLAB script that allows users to test the potential error included by using different combinations of discontinuous sand traps or measurement devices. The analysis is based on our continuous vertical flux profiles from the dataset.Overview: 本数据集文件（"DataFluxProfile.csv"）包含采用Sherman等人（2014）的方法，通过9目集沙阵列采集得到的沙量垂直通量剖面数据。本次采集工作于2022年10月开展，采样点位为巴西塞阿拉州热里科阿科阿拉（Jericoacoara）的三处野外监测场。 本次采集的连续剖面由垂直堆叠的9组集沙阵列获取，旨在评估使用BSNE、MWAC等非连续式集沙装置，或Wenglor叉形激光粒子计数器等替代设备时可能产生的测量误差。本次误差评估基于本数据集连续剖面的9个特征高度（https://doi.org/10.5281/zenodo.15700463）。 如需了解实验设置与数据分析的详细细节，请参阅配套学术论文《Measuring Aeolian Saltation Flux Profiles: Comparison of Methods》。 变量说明： 研究站点：巴西塞阿拉州热里科阿科阿拉的具体野外监测点位（详见论文中图1与图2）。 采集日期（mm/dd/yyyy）：数据采集的具体日期。 测量时长（单位：秒）：单组通量剖面测量的持续时间。 沙粒中值粒径（单位：微米）：采集沙粒的中值直径。 集沙器1（单位：克）：地表至25 mm高度区间内采集的沙量。 集沙器2（单位：克）：25 mm至50 mm高度区间内采集的沙量。 集沙器3（单位：克）：50 mm至75 mm高度区间内采集的沙量。 集沙器4（单位：克）：75 mm至100 mm高度区间内采集的沙量。 集沙器5（单位：克）：100 mm至150 mm高度区间内采集的沙量。 集沙器6（单位：克）：150 mm至200 mm高度区间内采集的沙量。 集沙器7（单位：克）：200 mm至250 mm高度区间内采集的沙量。 集沙器8（单位：克）：250 mm至350 mm高度区间内采集的沙量。 集沙器9（单位：克）：350 mm至450 mm高度区间内采集的沙量。 总沙量（单位：克）：地表至450 mm高度区间内采集的总沙量。 文件"FluxProfileCombinationTest.m"（DOI：10.5281/zenodo.15700463）为MATLAB脚本，可用于测试使用不同组合的非连续式集沙装置或测量设备时可能产生的误差，其分析基于本数据集的连续垂直通量剖面数据。
