2005-2015年珠三角对流层NO2柱浓度时空变化遥感监测
Spatio-temporal Change of Tropospheric NO2 Column Density over Pearl River Delta from 2005 to 2015
摘要
Abstract
Based on satellite derived NO2 column data from OMI, we analysed the characteristics of spatial and temporal distribution of tropospheric NO2 column density over Pearl River Delta from 2005 to 2015�Results demonstrate: ( 1 ) Tropospheric NO2 column density decreased at the annual rate of 4�25%, with the lowest column density 508�83×1013mole/cm2 in the year 2015, and with the highest column density 819�37 × 1013 mole/cm2 in the year 2007; it declined 12�11%compared with 2005 in 2010 and declined 26�28% compared with 2010 in 2015; ( 2) Tropospheric NO2 column density is high in the middle and low in the surrounding of Pearl River Delta; (3)The monthly mean value of tropospheric NO2 column density has significant cyclical change for years�The monthly mean value of June to September is usually low, and that of November to February is usually high.关键词
