Vertical Profiles of Aerosol Concentration in Conjunction with Simultaneous Measurements of the Vertical Profiles of Several Long Lived Tracers and Several Ozone Destroying...

9528028 Deshler在这个项目中，将使用气球携带的仪器在高达30公里的高度测量气溶胶的垂直剖面。这些测量将是主要由欧盟支持的气球运动的一部分。在两年的时间里，将在热带、北部中纬度和北部高纬度飞行中同时测量几种痕量气体、臭氧、水蒸气、几种含有氮和卤素的反应性自由基以及气溶胶的垂直剖面。这些测量将共同用于研究运输和光化学在控制自由基分布方面的重要性。将寻求关于横跨赤道对流层顶、从对流层顶至30公里、横跨副热带急流和横跨极地涡旋边缘的输送时间常数的具体动态信息。将获得关于极地和赤道的脱水机制、火山气溶胶和极地平流层云的尺寸分布以及北极涡旋冬季平均臭氧减少和反硝化的信息。

9528028 Deshler In this project, vertical profiles of aerosols will be measured using a balloon-borne instrument at altitudes up to 30 km. These measurements will be part of a balloon campaign supported primarily by the European Union. Over two years, simultaneous vertical profiles of several trace gases, ozone, water vapor, several reactive radicals containing nitrogen and halogen, and aerosols will be measured at tropical, Northern mid-latitude, and Northern high latitude flights. These measurements will be used collectively to investigate the importance of transport and photochemistry in controlling the radical distribution. Specific dynamic information will be sought concerning the time constants of transport across the tropopause at the equator, from the tropopause up to 30 km, across the sub-tropical jet, and across the edge of the polar vortex. Information will be obtained concerning the dehydration mechanisms at the pole and at the equator, the size distribution of volcanic aerosol and polar stratospheric clouds, and the average ozone reduction and denitrification in the Arctic vortex in winter.
