作为Solve-Teseo 2000运动的一部分，1999/2000年冬季在气球上对CFC-11(Dirac原位气相色谱仪和笛卡尔抓取取样器的飞行)、ClO和臭氧进行了测量。在这里，我们介绍了9次飞行的CFC-11数据，并首先将它们与战役期间飞行的其他仪器的数据进行了比较，然后与SlimCat 3-D CTM计算的垂直分布进行了比较。我们利用在航班上测得的CFC-11与臭氧的关系计算了1月底至3月初北极涡旋内部的臭氧损失，臭氧损失的峰值(1200ppbv)出现在3月初的440-470K区域，与已发表的其他经验估计值符合得很好。这里使用的三个独立气球示踪器数据集得出的臭氧损失之间也有很好的一致性。由测量得出的损失的大小和垂直分布与SlimCat计算的同一天基律纳上空的损失很好地吻合。
Balloon-borne measurements of CFC-11 (on flights of the DIRAC in situ gas chromatograph and the DESCARTES grab sampler), ClO and O3 were made during the 1999/2000 winter as part of the SOLVE-THESEO 2000 campaign. Here we present the CFC-11 data from nine flights and compare them first with data from other instruments which flew during the campaign and then with the vertical distributions calculated by the SLIMCAT 3-D CTM. We calculate ozone loss inside the Arctic vortex between late January and early March using the relation between CFC-11 and O3 measured on the flights, the peak ozone loss (1200 ppbv) occurs in the 440–470 K region in early March in reasonable agreement with other published empirical estimates. There is also a good agreement between ozone losses derived from three independent balloon tracer data sets used here. The magnitude and vertical distribution of the loss derived from the measurements is in good agreement with the loss calculated from SLIMCAT over Kiruna for the same days.
