The Application of AOD's Spectral Curve Parameter to Judgment of Aerosol Particle Size

  • 摘要: 当气溶胶谱满足Junge分布时,Angstrom指数 (α) 可以准确地描述粒子大小,但真实大气气溶胶很少完全满足这一条件,仅用α判断粒子大小会有较大出入。基于北京、香河、兴隆、太湖4个Aeronet观测站21世纪以来各站历时都超过1年的气溶胶光学厚度资料,获得5511组lnτ与lnλ的二次拟合参数a2a1,尝试找到一种结合αa2a1判断粒子大小的方法。结果表明:当气溶胶为粗粒子时 (Vfine/Vtotal<0.2),α均小于0.75,仅用α就可以较好地判断粒子大小,但当气溶胶以细粒子为主时 (Vfine/Vtotal>0.7),该方法会有较大出入,此时a2a1可以有效地辅助α判断粒子大小,α>0.75,a2<-0.5或a2<-0.5,a1<-1.0是较好的判据。此外,分析发现国外研究提出的用a2-a1判断粒子大小的方法效果并不理想,尤其在1<a2-a1<2的情况下,粒子的组成有多种可能。
