气溶胶粒径数密度谱的激光大气传输工程应用

Project Application of Size and Number Density Distribution of Aerosol Particle in Laser Atmosphere Transmission

气溶胶粒径数密度谱分布是激光大气传输计算的重要参量,鉴于气溶胶的时空变化和难于现场测量的特点,以实测数据为依据,从工程应用角度出发,使用数据拟合的方法得到气溶胶粒径数密度谱与能见度的函数表达式,并通过仿真计算验证该函数的实用性.

Size and number density distribution of aerosol particle is important parameter in calculating laser atmosphere transmission. The aerosol particle have characteristics of change by space-time and difficulty in measurement, therefore, according to measured data and from the project application, the function expression of size and number density distribution of aerosol particle were acquired by curve-fitting method. The validate practicability of this function was verified through simulation and calculation.
