Observation of ozone in the Arctic upper stratsophere

1.1995年在挪威斯皮茨卑尔根的NY Alesund用BT-5高空气球上的光学臭氧传感器观测了北极夏季平流层的臭氧廓线。两名工作人员被派往该地点进行观测。以下是四次发射，每次发射都获得了良好的数据。‘ECC on board’意味着ECC在同一个气球上进行比较测量，‘ECC on橡皮气球’意味着ECC与橡胶气球同时发射。2.与臭氧化学有关的大气次要成分的全球观测；1996年3月在瑞典木村用FTIR对北极冬季的HCl、HF、HNO_3、O_3、ClONO_2、CH_4和N_2O进行了测量。一名人员被派往现场。3.北极观测的结果，除基律纳的地面观测数据尚未处理外，结果表明：(1)用光学传感器和ECC臭氧探空仪得到的臭氧廓线在30公里以下吻合较好，在40公里附近有明显的结构，而ECC廓线在30公里以上随高度单调减小，表明在40公里以上也可以用光学方法获得臭氧廓线，而ECC在高海拔地区由于抽运效率低而变得不可靠。(2)包括1995年在内的两个夏季都获得了北极平流层上层以下的臭氧廓线。

1.Observation of ozone profiles in the arctic summer stratosphere was carried out at Ny Alesund in Spitzbergen, Norway in 1995 using an optical ozone sensor on board a BT-5 high altitude balloon.Two personnels were sent to the site for this observation.Four launches were as follows and good data were obtained for each launch.'ECC on board' means ECC was on the same balloon to make a comparative measurements and 'ECC on rubber balloon' means concurrent launch of ECC with a rubber balloon.2.Ground observation of ozone chemistry related atmospheric minor constituents ; HCl, HF,HNO_3, O_3, ClONO_2, CH_4 and N_2O in the arctic winter was made at Kimura, Sweden in March 1996 with a FTIR.One personnel was sent to the site.3.Results from observations in the arctic, except for the ground observation at Kiruna whose data have not been processed yet, have been examined as follows :(1) Comparison of ozone profiles obtained with an optical sensor and an ECC ozonesonde showed that both profiles agree well each other below 30km and that a distinct structure around 40km was seen in the optically obtained profile while ECC profile above 30km decreases monotonically with altitude.This indicates that ozone profiles can be obtained with the optical method even above 40km while ECC becomes unreliable due to its low pumping efficiency in high altitudes.(2) Ozone profiles up to the upper stratosphere in the arctic have been obtained in two summers including 1995.
