| 摘 要： | 利用2006年和2007年河北省机载粒子探测系统(PMS)获得的飞行探测资料,分析了石家庄地区春季上空大气气溶胶粒子的浓度垂直分布特征、不同高度上的谱分布和水平变化特征,并对粒子谱分布进行了负幂函数拟合.分析表明,霾天气下的气溶胶粒子数浓度高于晴天1个量级,达到104个/cm3;粒子平均直径为0.13~0.26mm;气溶胶粒子浓度水平变化受下垫面、云区等局地影响因子较大,受不同天气状况影响较小;负幂函数对细粒子谱分布有较好的拟合效果.

| Abstract: | The vertical profile of number concentration and size distribution of aerosol particles at different altitudes over Shijiazhuang area were analyzed based on aircraft measurements conducted in Hebei Province in 2006 and 2007.The size distributions were fitted with negative power function.The number concentration and size distribution of different heights were significantly different.The number concentration of aerosol particles in hazy days was one order of magnitude higher than that in the clean days,reachi... |
