摘要
对国产臭氧探空仪从2001年4月到2004年9月在北京观测的臭氧垂直分布数据的质量进行分析. 对国产臭氧探空仪系统基本测量数据(包括电化学反应池池温、臭氧最大分压及其所在的高度、对流层顶的温度和高度)进行初步分析,结果发现国产臭氧探空仪的稳定性仍需进一步提高.与地面多谱森臭氧总量观测相比,国产臭氧探空积分的总量普遍要高,2002年至2003年之间的差别范围基本上保持在±20%以内.与国际普遍使用的双池型电化学(ECC型)臭氧探空观测结果相比,国产臭氧探空观测臭氧分压在15 km以下、25～30 km两个高度范围,均要高于ECC测值.分析结果建议国产臭氧探空仪应尽快参与由全球大气本底监测(GAW)技术主持的世界臭氧探空仪标定中心进行标定, 并在现有的技术条件下, 向双池型电化学型臭氧探空仪这一方向发展.
Quality analysis on the vertical distribution data observed by the Chinese-made ozone sonde system over Beijing from April 2001 to September 2004 is presented. The basic parameters observed by the system including the temperature of electronic chemistry cell in the sonde, the maximum of atmospheric ozone partial pressure and its altitude, the temperature and altitude of tropopause indicate that the stability of the sonde system needs to be improved. The integrated column ozone from the sonde system is generally higher than that of observed by the ground-based Dobson spectrophotometer, and the difference of them is within ± 20% from 2002 to 2003. 11 times simultaneous comparison measurements show that the ozone partial pressure below 15 km and in 25--30 km observed by Chinese-made ozonde sonde system are higher than that observed by the ECC ozone sonde system with double cells which is extensively used. Also, the result suggests that the Chinese-made ozone sonde system participate the international calibration campaign organized by the Global Atmospheric Watch World Meteorological Organization（GAW/WMO）. With the certain technological availability, the single cell in Chinese-made ozone ~nde system is recommenede to be updated by double cells.
