三极地区0.1º气溶胶光学厚度数据集（2000-2020）

2000-2020年三极地区0.1º气溶胶光学厚度数据集(也称为“Poles AOD Collection 1.0”气溶胶光学厚度（AOD）数据集），结合Merra-2模式数据与MODIS卫星传感器AOD制作，数据覆盖时间从2000年到2020年，时间分辨率为逐日，覆盖范围为“三极”（南极、北极和青藏高原）地区，空间分辨率为0.1度。通过实测站点验证表明，数据相对偏差在35%以内，可有效提高极区气溶胶光学厚度的覆盖率和精度。

The 0.1° Aerosol Optical Depth (AOD) Dataset over the Three Poles Region from 2000 to 2020 (also referred to as the "Poles AOD Collection 1.0" Aerosol Optical Depth Dataset) is developed by integrating MERRA-2 reanalysis data and AOD products retrieved from the MODIS satellite sensors. This dataset spans the period from 2000 to 2020 with a daily temporal resolution, and covers the Three Poles region including Antarctica, the Arctic and the Tibetan Plateau at a spatial resolution of 0.1°. Validated via in-situ station observations, the dataset exhibits a relative bias within 35%, which effectively enhances the coverage and accuracy of AOD data in polar regions.
