| 摘 要： | 针对目前雨中衰减模型在紫外光波段的适用局限性，介绍了考虑雨滴对光传输的遮挡作用时光的传输衰减模型，通过与Modtran数据及相关文献比较验证了模型在紫外光波段的适用性，分析了降雨时影响紫外光衰减的主要因素，表明降雨时能见度对紫外光的衰减影响较大，并结合实际的降雨情况考虑能见度的影响提出了紫外光在雨中的传输衰减计算模型。

| Abstract: | Aiming at the application limitation of existing attenuation model for ultraviolet transmission through rain, the non scattering model of attenuation for optical transmission through rain is described. The model applicability for ultraviolet transmission is proved as compared with relative literature and data from Modtran. The main factor causes attenuation for ultraviolet transmission through rain is analysed. The result indicates that thevisibilitymakes great effect on ultraviolet attenuation. Based on realrainfall, acaleulation model for attenuation in view of visibility for ultraviolet transmission through rain is provided. |
