本文利用2022年8月至2024年12月的大气臭氧探空资料,分析了北京地区边界层、对流层、平流层臭氧浓度的平均月变化以及季节变化等。结果显示:大气边界层下层1月臭氧浓度值最小为29.9 × 10−9 (体积分数,下同),最大值为6月达到了88.24 × 10−9,1月到6月逐月递增之后逐渐递减,臭氧浓度随高度逐渐增长;大气边界层到对流层顶臭氧浓度随高度先减少,接近对流层顶浓度增长;平流层下部臭氧浓度偏低,之后逐渐增长在20~25 km出现极大值然后逐渐递减。季节变化特征为:对流层夏季臭氧浓度最大,冬季最小。边界层季节之间臭氧浓度积分量相差幅度更大,四个季节均呈现持续增长的趋势,冬春两季对流层顶偏低;平流层冬春两季臭氧浓度偏大,夏秋两季偏小。臭氧浓度极大值出现的高度略有波动。对流层、平流层臭氧浓度与霾的关系为:近地面春秋两季有霾情况下臭氧浓度更高,冬季无霾情况下偏高。对流层上部及平流层无霾时臭氧浓度更高并且冬春两季有霾时浓度极值出现在更高的位置,秋季出现在偏下的位置。The paper uses the atmospheric ozone sounding data from August 2022 to December 2024 and analyzes the ozone concentration average monthly change and seasonal variation of the bounding layer, troposphere and stratosphere in Beijing. The results show that the ozone concentration of the bounding layer gets the minimum value which was 29.9 × 10−9 in January while gets the maximum value in June which was 88.24 × 10−9. From January to June, the ozone concentration increased first and then decreased. The ozone concentration would increase with the height. From the bounding layer to the top of the convective zone, the ozone concentration at first decreases with the growth in the height and then increases. The ozone concentration in the space under the stratosphere is very low but increases with the height and gets the maximum value when the altitude r
