摘    要:基于OMI数据产品OMITO3e,提取了中国2005—2011年臭氧总量信息,并对其空间分布和时间演变特征加以分析。研究结果表明:在空间上,中国臭氧总量呈现北高南低、东高西低的特征,峰值出现在东北地区,夏秋季节在青藏高原存在明显的臭氧低谷;在纬度上,中国东北部臭氧总量纬向偏差为正,在其他区域为负;在时间上,中国臭氧总量呈现明显的季节变化特征,冬春季节高,夏秋季节低,最大值多出现在3月,最低值多出现在10月。

关 键 词:OMI  臭氧总量  季节变化

Abstract:Total column ozone over China from 2005 to 2011 was derived from OMI (Ozone Monitoring Instrument) ozone product, OMITO3e. And then its spatial pattern and temporal variation was analyzed. Results show that the total column ozone in the north and east of China is higher than that in the south and west, respectively, with its peak occurring in the northeast, and a low center of total column ozone over Tibetan Plateau was observed in summer. The deviation of total column ozone from the zonal mean is positive in the northeast of China but negative in other parts of China. Total column ozone over China varies significantly with season of the year, higher in winter and spring, and lower in summer and autumn. The largest value mainly appears in March, while the smallest value mostly appears in October.
Keywords:OMI  total column ozone  seasonal variation
