In Situ Measurements of Stratospheric Ozone from Long Duration Balloons during Concordiasi

科罗拉多大学博尔德分校的研究人员将建造和部署一些低功率紫外线测光仪，放置在长时间持续的平流层超压(恒容)气球上，该气球将于2009年在南极洲麦克默多进行的美法联合CONCORDIASI项目(http://www.cnrm.meteo.fr/concordiasi/)期间发射。当气球在南极极地涡旋中漂移时，光度计将被用来测量高空中的臭氧(O3)浓度。从这一平台的独特优势来看，在南半球春季(9月至11月)开始时获得的近拉格朗日臭氧测量结果将使我们能够详细观察正在形成的年度臭氧消耗事件。气球飞行数据将与模型预测进行比较。对研究进展的讨论，包括自《蒙特利尔议定书》通过以来在扭转季节性臭氧消耗事件方面的进展，将与丹佛科技学院的中学和高中课堂活动协调。“该奖项是根据2009年美国复苏和再投资法案(公共法律111-5)资助的。”

AbstractResearchers from the University of Colorado at Boulder will construct and deploy a number of low powered UV photometers to be placed on long duration stratospheric super pressure (constant volume) balloons to be launched during the joint US-French CONCORDIASI project (http://www.cnrm.meteo.fr/concordiasi/ ) to take place from McMurdo, Antarctica in 2009. The photometers will in turn be used to measure in situ ozone (O3) concentrations aloft, as the balloons drift in the Antarctic polar vortex. From the unique vantage point of this platform, the resulting near-Lagrangian ozone measurements, acquired at the onset of the austral spring (Sept-Nov), will allow detailed observation of the developing annual ozone depletion event. Balloon flight data will be compared with modeled predictions. Discussion of the progress of the research, including progress towards reversal of seasonal ozone depletion events since adoption of the Montreal Protocol, will be coordinated with mid level and high school classroom activities at the Denver School of Science and Technology."This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)."
