摘要

摘要: 基于Monin-Obukhov相似性理论，采用MARIAH算法，利用成都和茂名两个地区、两个高度层上的温度、湿度、风速等常规气象参数估算折射率结构常数，并对估算值与温度脉动仪测量值进行比较分析。结果显示：利用常规气象参数估算得到的成都与茂名的折射率结构常数在变化趋势及量级上基本符合温度脉动仪测量值。成都和茂名的折射率结构常数估算值与测量值的相关系数分别为0.86与0.92，平均绝对值偏差分别为0.410与0.414。因此，采用MARIAH算法估算陆地和近海面大气光学折射率结构常数是可行的；茂名中午时刻的折射率结构常数峰值比成都大一个量级。

Abstract: The refractive index structure constant is estimated and compared with measured values from micro-thermometer by using the meteorological parameters of Chengdu and Maoming, such as temperature, humidity and wind speed on two altitudes. The estimated model adopts MARIAH algorithm, which is based on the Monin-Obukhov similarity theory. The result shows that it is feasible to calculate the structure parameter by MARIAH algorithm. The trend and order of magnitude of the estimated structure constant fit well to that of the measured data. The correlation coefficients between estimated and measured values of two places are 0.86 and 0.92 while the mean absolute error values are 0.410 and 0.414 respectively. Besides, the estimated structure constant of Maoming is one order of magnitude larger than that of Chengdu.
