摘要
依据液态水介电常数模型,在满足瑞利散射近似的条件下,利用普遍接受的经验公式和Salonen模型获得了不同类型云、雾的水滴密度/含水量,模拟计算了云和雾粒子对0.01-1THz太赫兹辐射的比衰减系数,并继而分析了低空的云雾衰减系数随温度、含水量等的变化规律。
Based on the liquid water dielectric constant model, under similar conditions to satisfy the Rayleigh scattering, using of the widespread empirical formula and Salonen model gained different types of clouds, fog droplets density / moisture, simulated the ratio attenuation coefficient of clouds and fog particle to the 0.01-1THz terahertz radiation, and then analyzed the low-altitude clouds attenuation coefficient variation with temperature, moisture, etc.
