基于扫描粒径的原理,介绍了测量高粒径分辨率气溶胶活化率曲线的方法。给出了改进的数据反演算法,能较好地反演出气溶胶和云凝结核的数浓度谱分布,以及气溶胶分档活化率。在大气气溶胶的外场观测中对该方法进行了检验。
A method for measuring size-resolved activation ratios with high size resolution is introduced.The number size distributions of aerosols and cloud condensation nuclei,along with the size-resolved activation ratios,can be inverted with an improved inversion algorithm.The method was tested during field measurements for atmospheric aerosols.
