中文摘要	为探讨天山南北绿洲城市重污染期对流层NO_2的垂直柱浓度(VCD)分布特征,利用多轴差分吸收光谱仪(MAXDOAS)对20152017年重污染期间天山北坡乌鲁木齐、石河子、小城市博乐及南坡中等城市库尔勒、小城市和田市区进行定点监测和车载移动监测,研究NO_2VCD时空分布规律,并与同期臭氧监测仪(OMI)卫星反演提供的NO_2VCD进行对比分析。结果表明,天山南北绿洲城市NO_2VCD日变化均呈早晚高,中午低趋势,其中最大4h(15:0019:00)NO_2VCD为乌鲁木齐市>库尔勒市>石河子市>和田市>博乐市;移动监测数据表明,城市对流层NO_2VCD在风向稳定且具有较高风速的监测日时,下风向浓度通常高于上风向,且车流量较高的立交桥与道路交汇处容易出现高值;因天山南北绿洲城市的地形不同,气象因子的差别(尤其是风场)是导致对流层NO_2VCD浓度差异的重要原因;MAX-DOAS监测的NO_2VCD与OMI卫星反演NO_2VCD具有较好的一致性。
英文摘要	In order to investigate the distribution characteristics of tropospheric NO_2vertical column density (VCD)in oasis city of Xinjiang,this paper selected northern slopes of the Tianshan Mountains Urumqi,medium-sized city Shihezi,small city Bole,and southern slope medium-sized city Korla,small city Hotan as study area,and using multi axis differential optical absorption spectroscopy (MAX-DOAS)technology of fixed and mobile system to monitor the NO_2VCD during heavy air pollution period from 2015to 2017.The monitored data were also compared with NO_2VCD provided by Ozone Monitoring Instrument(OMI)satellite inversion during the same period.The results showed that the diurnal changes of NO_2VCD in these cities werehigh in the morning and evening,low in the noon,and the maximum 4h (15:00-19:00)NO_2VCD was followed the order of Urumqi>Korla>Shihezi> Hotan>Bole;The mobile MAX-DOAS data showed that under strong winds of constant direction,urban tropospheric NO_2VCD was relative higher in the downwind,and the maximum value was always found at overpasses and road intersections where had high volumes of traffic.Differences in the meteorological factors and industrial structures of oasis cities were the main cause of varying NO_2VCD;the MAX-DOAS measured NO_2VCD and OMI observed NO_2VCD had good agreement.
