Data for: Spatial-temporal variations and trends of aerosol optical depth over China during 2000-2017 using the MODIS C6 Dark Target and Deep Blue merged aerosol product

Seasonal, and yearly mean data, derived from the NASA MODIS high-resolution product combined with DT (Dark Target) and DB (Deep Blue) MODIS AOD algorithms. Spearman test for each point in the entire region.

季节性及年度平均数据，源自美国国家航空航天局（NASA）中分辨率成像光谱仪（MODIS）高分辨率产品，结合了暗目标（DT, Dark Target）与深蓝（DB, Deep Blue）MODIS气溶胶光学厚度（AOD）算法；对整个区域内的每个点进行斯皮尔曼检验（Spearman test）。
