Data for: A regional, size-dependent, and causal effective medium model for Asian and Saharan mineral dust refractive index spectra

First and second moments of complex refractive index spectra based on the Bruggeman effective medium approach for Asian and North African mineral dust aerosols.

The wavelength spectrum and resolution is given in the file wavelength_range.txt

Availabel regions are:
- Northern Sahara
- Southern Sahara
- West Asia (Gobi desert)
- East Asia

The standard deviation of the spectra for each region is given in files with the _stdv_ designation. Files containing mean spectra are unmarked.
The moments have been computed based on the size distributions published in Dubovik et al. (2002).

基于布鲁根曼有效介质方法，对亚洲及北非矿物尘埃气溶胶的复折射率光谱的一阶和二阶矩进行描述。波长谱及分辨率详见文件 wavelength_range.txt。可供获取的区域包括：北撒哈拉、南撒哈拉、西亚洲（戈壁沙漠）以及东亚。各区域的谱标准差由带有 _stdv_ 标识的文件提供，含有平均光谱的文件未作标记。这些矩是根据Dubovik等人（2002年）发表的尺寸分布计算得出的。
