A Set of Empirical Formulas for Calculation of Atmospheric Dispersion Coefficients

Journal: Transactions of Beijing Institute of Technology

Abstract: 用Marquardt法对D.Bruce Turner给出的大气扩散系数数据进行拟合,发现在0.01~100.00km范围内水平方向上的扩散系数可以用一个5参数经验公式表示; 垂直方向上的扩散系数也可以用5参数方程计算,但需要分成两段分别进行拟合和计算. 拟合结果与文献中数据之间的最大绝对误差小于40m,最大相对误差小于5%.
