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)."

科罗拉多大学博尔德分校的抽象搜索者将构建和部署许多低功率的紫外线光度计，将放置在长持续时间的平流层超压力（恒定体积）气球上，将在联合US-FRENCH CONCORDIASI PROVECT（http://wwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww.cnrm.fr/concordiasi tocks of Compand ofcement ock ock opception tock of Concordiasi concordiasi Project中）。随着气球在南极极性涡流中漂移，光度计将依次用于测量原位臭氧（O3）浓度。 从这个平台的独特有利位置，在澳大利亚春季（9月-NOV）开始时获得的近lagrangian臭氧测量值将允许详细观察开发的年度臭氧消耗事件。气球飞行数据将与建模的预测进行比较。讨论这项研究的进步，包括自蒙特利尔协议采用以来季节性臭氧耗竭事件的进展，将与丹佛科学技术学院的中级和高中课堂活动协调。
