Dust composition dataset compiled from literature

This dataset is compiled of available measured dust composition data collected from literature with detailed data selection and processing for the JGR paper "A Global-scale Mineral Dust Equation" by Liu et al (2022). It includes 7 worksheets providing the measured elemental composition data used to calculate elemental ratios, measured mineralogical composition data used to estimate the contribution of other types of carbonates apart from calcite and to examine the size effect on elemental ratios and carbonate content.

本数据集由公开文献中可获取的实测粉尘组分数据汇编而成，经严格的数据筛选与处理流程，用于支撑Liu等人2022年发表于《地球物理学研究杂志》（Journal of Geophysical Research，简称JGR）的论文《全球尺度矿物粉尘方程》（A Global-scale Mineral Dust Equation）。该数据集包含7个工作表，涵盖用于计算元素比值的实测元素组分数据，以及用于估算方解石以外其他碳酸盐类的贡献、并检验粒径效应对元素比值与碳酸盐含量影响的实测矿物组分数据。
