| 摘 要： | 根据中山站 Brewer臭氧光谱仪的观测结果 ,对中山站地区近六年春季臭氧低值的特征进行研究 ,并与 TOMS卫星观测结果进行了对比分析。分析表明中山站春季臭氧值的逐日变化与极地涡旋动力过程有密切联系。Brewer和 TOMS观测结果总体上接近 ,但 TOMS要略高于地基观测结果 6～ 1 0 DU。在春季臭氧低值期间 ,UV- B测值要高于夏至时的 UV- B测值 ,30 0～30 5nm波段的 UV- B辐射强度比 32 0～ 32 5nm波段更易受春季臭氧低值的影响

| Abstract: | WT5BZ]Based on the 6 year total ozone data set from the observations by using the Brewer ozone spectrophotometer and the TOMS, an summarily analysis study on the spring ozone depletion at Zhongshan Station(69.37°S,76.38°E),Antarctica has been presented in this paper. Our work confirms that the large ozone depletions over Zhongshan Station are associated with the dynamical process of the polar vortex, and this makes the large daily ozone variations during the spring period. Data set from the Brewer and TOMS is generally consistent with each other, however, TMOS data set is about 6~10DU higher than that of Brewer's observations. Surface global weighted UV B dose rate is higher in spring season than that on the summer solstice due to the anomalous spring ozone depletion. UV B irradiance within 300-305nm band is more sensitive to the ozone depletion than that within 320-325nm band. WT5HZ] |
