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)."

美国科罗拉多大学博尔德分校的研究人员将建造和部署一批低功率紫外线光度计，这些光度计将放置在2009年在南极洲麦克默多进行的美法联合CONCORDIASI项目（http：//www.example.com）期间发射的平流层长时间超压（定容）气球上。www.cnrm.meteo.fr/concordiasi/当气球在南极极涡中漂移时，光度计将依次用于测量高空臭氧（O3）浓度。 从这个平台的独特Vantage来看，在南方春季（9月至11月）开始时获得的近拉格朗日臭氧测量结果将使人们能够详细观察每年发生的臭氧消耗事件。气球飞行数据将与模型预测进行比较。关于研究进展的讨论，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取得的进展，将与丹佛科学技术学院的中级和高中课堂活动协调进行。“该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。"
