Dataset for evaluating the performance of LASS sensors in estimating wind-blown sand flux rate

This dataset was obtained from a series of laboratory sand drop experiments.

There are two Excel files in this dataset. There are six spreadsheets for each file. The spreadsheet name indicate the particle size range, e.g. '0.14-0.25 mm' is for sand with sizes ranging from 0.14 to 0.25 mm; 'unsieved' is for original sand sample without sieving. The field names used in these spreadsheets are explained below:

Q(kg m-2 s-1): Sand flux rate in kg m-2 s-1
Vr_top: Vr values for top LASS
Vr_bot: Vr values for bottom LASS

本数据集源自一系列实验室落砂实验。

该数据集包含两份Excel文件，每份文件内含六个工作表。工作表名称标注了对应砂粒的粒径范围，例如"0.14-0.25 mm"对应粒径介于0.14 mm至0.25 mm之间的砂粒；"unsieved"指代未经筛分的原始砂样。以下对各工作表内使用的字段名称进行说明：

Q(kg·m⁻²·s⁻¹)：单位为kg·m⁻²·s⁻¹的砂流通量；
Vr_top：顶层LASS的Vr值；
Vr_bot：底层LASS的Vr值。
