| 摘 要： | 利用OMI卫星反演数据分析了2005—2014年中国中东部地区对流层臭氧变化趋势.结果表明,近10年来对流层臭氧总柱浓度混合比例较稳定,但近地面浓度明显增加,特别是在冬季臭氧上升速度达40%.同时分析了京津冀、长三角、珠三角地区10个重点城市的臭氧数据,发现京津冀地区的臭氧涨幅超过其他两个地区,其中,长三角地区臭氧混合比例最高,而珠三角地区相对较稳定.利用臭氧激光雷达和地面臭氧监测数据对卫星反演结果进行比较显示了较好的一致性,证明使用卫星反演的数据来研究长时间范围内近地层的臭氧变化是一种可行的方法.

| Abstract: | OMI satellite data from 2005 to 2014 were analyzed to study the tropospheric ozone trend in mid-east China. The results showed that the mixing ratios of tropospheric ozone column were fairly stable but that of ground-level obviously increased, especially in winter by about 40%. Ground-level ozone of ten major cities in Beijing-Tianjin-Hebei region, Yangtze River Delta region and Pearl River Delta region were investigated. It was found that the increment of Beijing-Tianjin-Hebei region over the decade was larger than those of the other two regions. Yangtze River Delta region had the highest ozone mixing ratio while Pearl River Delta region kept quite stable. Ozone lidar and ground ozone monitoring data were compared to satellite retrieval results and showed reasonable consistency, which proved that satellite retrieval was a feasible way to study ground ozone trend over a long period. |
