摘要/Abstract

摘要：

基于OMI(Ozone Monitoring Instrument, OMI)卫星传感器监测得到的2006年1月-2014年12月南京都市圈对流层NO2柱浓度数据和土地利用类型数据，利用余弦曲线函数和HYSPLIT后向轨迹模型，分析了研究区对流层NO2时空分布特征以及污染物的来源。研究发现，2006-2014年南京都市圈对流层NO2柱浓度呈现出逐年增长的趋势和冬高夏低的季节变化特征；研究区对流层NO2污染物主要来自两个方面：大气气流的输送作用影响了研究区对流层NO2季节性变化；不同的土地利用类型影响了南京都市圈的对流层NO2柱浓度。

关键词: OMI, 对流层NO2, HYSPLIT模型, 时空变化

Abstract:

The spatio-temporal characteristics and pollution sources of NO2 in Nanjing metropolitan area are analyzed by using cosine curve function and HYSPLIT model of back trajectory analysis, on the basis of NO2 column densities data of the Ozone Monitoring Instrument (OMI) from January 2006 to December 2014 and land use type data. The results indicate that tropospheric NO2 column densities in study area increased distinctly year by year from 2006 to 2014 and showed obvious seasonal variation, i.e. highest in winter while lowest in summer. There are mainly two aspects of tropospheric NO2 contaminant sources in study area. The one is the effect of atmospheric transport affecting the seasonal variation of NO2, and the other is that different land use types have great impact on column density of NO2.

Key words: Ozone Monitoring Instrument, tropospheric NO2, HYSPLIT model, temporal and spatial variation
