The Asian monsoon, a pathway from one of the highest polluted regions on Earth into the stratosphere and its impact on the climate is currently a highly discussed topic. Especially enhanced aerosol concentrations in the Asian monsoon anticyclone (ATAL) have recently been found with satellite measurements and have not been detected before 1998. The ATAL has not sufficiently been analyzed yet and is subject of the proposed project. During the past months/year high resolution instruments on board a research aircraft and balloons obtained aerosol measurements in terms of composition, size, shape and concentration exactly in the area of interest, the Asian monsoon. Those new measurements complement the wider picture of satellite based measurements. During the proposed project various satellite measurements and the highly resolved airborne insitu measurements will be combined, compared and analyzed for the properties of the ATAL (quantity, chemical composition and trend). Furthermore, those obtained information will be implemented and contributed to a wider model study comprised of two atmospheric models, improving our knowledge about why the ATAL developed, what its impact is on the climate and what its source regions are. The project will improve our knowledge about the ATAL, the Asian monsoon, its role in the Earth’s atmosphere and its impact on the climate.

亚洲季风是从地球上污染最严重的地区之一进入平流层的途径，它对气候的影响目前是一个高度讨论的话题。特别是在亚洲季风反气旋（ATL）气溶胶浓度增强最近被发现与卫星测量，并没有在1998年之前检测到。安乐尚未得到充分的分析，是拟议项目的主题。在过去的几个月/一年里，一架研究飞机和气球上的高分辨率仪器准确地在亚洲季风这一感兴趣的地区获得了气溶胶成分、大小、形状和浓度的测量结果。这些新的测量补充了更广泛的卫星测量。在拟议的项目期间，将结合各种卫星测量和高分辨率的机载原位测量，比较和分析ATAL的特性（数量，化学成分和趋势）。此外，这些获得的信息将被实施，并有助于一个更广泛的模型研究，包括两个大气模型，提高我们的知识，为什么安乐发展，它对气候的影响是什么，它的源区是什么。该项目将提高我们对亚洲季风、亚洲季风在地球大气中的作用及其对气候的影响的认识。
