To investigate the consistency and difference between AERONET version 2 and 3 data set in the Korean peninsula, we compared several aerosol optical properties for 12 Korean AERONET sites having at least 2-year measurement records. Generally, both version products have similar patterns, but we sometimes found a little regional difference. While the aerosol optical depth (AOD) is analogous between version 2 and 3, the version difference of single scattering albedo (SSA) is the largest. Ångström exponent (AE) and fine mode fraction (FMF) values are sometimes different in maritime conditions. Two AERONET sites in Seoul (Seoul_SNU and Yonsei_Univ) have some differences between version 2 and 3, probably related to the higher sensitivity of version 3 data to the fine mode particle. Since parameters revealing the aerosol radiative property (e.g., SSA) and size information (e.g., AE and FMF) show some version differences regionally, we compared the result of aerosol type classification using these parameters. As a result, we found that the version difference of aerosol size and radiative property can induce the different diagnosis of locally dominant aerosol types. In spite of these findings, consistency between version 2 and 3 is quite large. Thus, regional patterns of aerosol optical properties previously found based on AERONET version 2 look still valid in the Korean peninsula.

为了调查朝鲜半岛AERONET版本2和3数据集之间的一致性和差异，我们比较了具有至少2年测量记录的12个韩国AERONET站点的几种气溶胶光学特性。通常，两种版本的产品都具有相似的模式，但是有时我们会发现一些地区差异。虽然版本2和版本3之间的气溶胶光学深度（AOD）相似，但单散射反照率（SSA）的版本差异最大。在海上条件下，Ångström指数（AE）和精细模式分数（FMF）值有时会有所不同。首尔的两个AERONET站点（Seoul_SNU和Yonsei_Univ）在版本2和版本3之间存在一些差异，这可能与版本3数据对精细模式粒子的更高敏感性有关。由于参数揭示了气溶胶的辐射特性（例如，SSA）和尺寸信息（例如AE和FMF）在区域上显示出一些版本差异，我们使用这些参数比较了气溶胶类型分类的结果。结果，我们发现气溶胶大小和辐射特性的版本差异可以引起对局部优势气溶胶类型的不同诊断。尽管有这些发现，但版本2和版本3之间的一致性还是很高的。因此，以前基于AERONET版本2发现的气溶胶光学特性的区域模式在朝鲜半岛仍然有效。尽管有这些发现，但版本2和版本3之间的一致性还是很高的。因此，以前基于AERONET版本2发现的气溶胶光学特性的区域模式在朝鲜半岛仍然有效。尽管有这些发现，但版本2和版本3之间的一致性还是很高的。因此，以前基于AERONET版本2发现的气溶胶光学特性的区域模式在朝鲜半岛仍然有效。
