自 1990 年左右以来，地球表面的陆地和海洋太阳辐射有所增加（“全球增亮”）。对来自地球静止和极轨卫星的各种全球（仅限海洋）气溶胶和（全球）云数据集进行分析，以确定这些数量的变化是否按照“全球增亮”发生，并分析这些变化的全球分布。分析中采用了变化点检测和趋势分析。从 20 世纪 80 年代中期到 2000 年代中期，气溶胶光学深度被发现在 90 年代初开始下降，而云数据集的趋势却不一致。埃指数数据似乎表明污染发生了变化。引用：Cermak, J.、M.

Solar radiation at the Earth surface has increased over land and ocean since about 1990 ('global brightening'). An analysis of various global (ocean only) aerosol and (global) cloud data sets from geostationary and polar orbiting satellites is performed to determine whether changes in these quantities have occurred in accordance with 'global brightening', and to analyse the global distribution of these changes. Change-point detection and trend analysis are employed in the analysis. In a period from the mid-1980s to the mid-2000s, aerosol optical depth is found to have started declining in the early 1990s, while cloud data sets do not agree on trends. Angstrom exponent data seem to suggest changes in pollution. Citation: Cermak, J., M. Wild, R. Knutti, M. I. Mishchenko, and A. K.
