通过变差函数分析AERONET数据以辅助气溶胶验证和比较研究的补充信息

这包含了数据集及其描述，用于提交给《地球与空间科学》期刊的论文“多长时间才算太长？利用变差函数分析AERONET数据以辅助气溶胶验证和比较研究”。本研究调查了由于数据集之间观测时间的差异而引入到气溶胶光学性质比较（例如AERONET地面观测、卫星检索或模型模拟之间的比较）中的不确定性。这个不确定性源在历史上一直被忽视，但在某些情况下可能很重要。
期刊政策规定，支持信息数据集不能再与论文一起存档，而应该上传到一个单独的存储库中。因此，我在这里上传了这些数据。
这个数据集包括一个描述数据集的PDF文件，然后是两个包含数据（ASCII格式）的zip压缩包。总大小约为10 MB。这些数据文件允许复制本文中的分析结果，并使研究人员能够估计他们自己涉及AERONET站点的分析中的时间不匹配不确定性。

This contains the dataset and its accompanying description, for the paper submitted to the journal *Earth and Space Science* titled "How Long Is Too Long? Using Variogram Analysis of AERONET Data to Support Aerosol Validation and Comparative Studies". This study investigates the uncertainty introduced into comparisons of aerosol optical properties—such as comparisons between AERONET ground-based observations, satellite retrievals, or model simulations—by differences in observation timing across datasets. This source of uncertainty has historically been overlooked, yet can be significant in certain cases. According to the journal's policy, supporting information datasets can no longer be archived alongside the paper and must instead be uploaded to a separate repository. I am therefore uploading these data here. This dataset includes a PDF file describing the dataset, followed by two ZIP compressed packages containing data in ASCII format. The total size is approximately 10 MB. These data files enable replication of the analytical results presented in this paper, and allow researchers to estimate the temporal mismatch uncertainty in their own analyses involving AERONET sites.
