摘要
提出了一种大气光学折射率结构常数的数值模式。一次输入日期、时间、经纬度、温度、湿度、风速、粗糙度、土壤参数 ,云量等相关参数 ,可得到 2 4h内的温度、湿度、风场、折射率结构常数等量。通过与实测对比表明 ,无论是月平均折射率结构常数还是某天的折射率结构常数 ,模式计算与实测数据都符合得很好。模式计算的向下总辐射通量与实测数据基本一致。
A numerical model of atmospheric optical refractive index structure parameter is presented. The input data for this model consisted of date, time, latitude and longitude, temperature, humidity, windspeed, roughness length, soil parameter, and cloud parameter, 24 h forecasts of the time variation of refractive index structure parameter near the surface will be produced. Comparison of measured and modeled results indicated that refractive index structure parameter both monthly and daily averaged can give consistent results. Comparison of total downward radiative flux modeled and measured is generally quite satisfactory.
