摘要:
利用MODIS气溶胶光学厚度(AOD)估算了近地面PM2.5质量浓度,统计了2004—2015年江西省南昌市PM2.5质量浓度的空间分布特征和年、季变化特征.研究发现:南昌市中部即中心市区为PM2.5高值区,东部和西部城郊地区为低值区.PM2.5最高值通常出现在冬季,秋季次之,最低值则通常出现在夏季.2009年之后南昌市PM2.5质量浓度逐年下降,2014年出现短暂反弹上升,而至2015年达到自2004年以来的最低值(48 μg·m-3).研究结果表明:利用卫星遥感技术可以有效地评估南昌市的空气质量水平.
Abstract:
Using MODIS aerosol optical depth(AOD)to estimate the near ground PM2.5 mass concentration,the spatial distribution characteristics and seasonal variation characteristics of PM2.5 mass concentration in Nanchang from 2004 to 2015 years are calculated.The results show that the central urban area of Nanchang is a PM2.5 high value area,and the eastern and western suburbs are low value areas.The highest values of PM2.5 usually appear in winter,followed by autumn,and the lowest values usually appear in summer.After 2009,PM2.5 mass concentration in Nanchang decreases year by year,and rebounds in 2014,reaches its highest level in 2014,reaches its lowest value in 2015(48 μg·m-3)after 2004.The results show that the satellite remote sensing technology can effectively assess the air quality level in Nanchang.
