O3, NO2, CH2O, O4, BrO, OCIO, IO and OIO profile measurements in the upper troposphere and lower stratosphere aboard balloon (MIPAS-B and LPMA) and aircraft (Geophysica) platforms

该建议旨在测量紫外/可见光吸收痕量气体的剖面，这对上层对流层和下层平流层臭氧的光化学特别有意义。O_3、NO_2、CH_2O、O_4、BrO、OCIO、IO和OIO的轮廓将使用新开发的和已经得到验证的准原位肢体扫描UV/可见光DOAS光谱技术来灵敏地检测。该仪器将部署在两个不同的气球有效载荷(MIPAS-B和LPMA/IASI)和一架研究飞机(地球物理卫星)上，这些活动是在国际和国家资助的研究项目(EU-Scout-=3；EU-AMMA；ENVISAT验证，..)内规划的各种实地活动期间进行的。这些运动是在提案的时间范围内安排的，即从2005年底到2008年。测量的数据将与在主机平台上同时执行的一套更大的相关测量一起解释。数据解释的重点将是卤素氧化物对对流层上层和平流层下层臭氧光化学的作用。

The proposal aims at profile meassurements of UV/visible absorbing trace gases, which are of particular interest for the photochemistry of upper troposheric and lower stratospheric ozone. Profiles of O3, NO2, CH2O, O4, BrO, OCIO, IO and OIO will be sensitively detected using the newly developed and already validated technique of quasi-in-situ Limb scanning UV/visible DOAS spectroscopy. The instrument will be deployed on two different balloon payloads (MIPAS-B and LPMA/IASI) and a research aircraft (Geophysica) during various field campaigns which are planned within internationally and nationally funded research projects (EU-SCOUT-=3; EU-AMMA; ENVISAT validation,..). The campaigns are scheduled within the time frame of the proposal, i.e. from late 2005 to 2008. The measured data will be interpreted together with a larger suite of correlative measurements that are simultaneously performed on the host platforms. Particular focus of the data interpretation will be put on the role of halogen oxides for the ozone photochemistry of the upper troposphere and lower stratosphere.
