摘要

能见度是气象、环境和交通观测重要要素,目前不同原理和型号的前向散射能见度仪没有统一的测试环境和定标标准,导致测量结果差别大。为实现前向散射能见度仪统一测试环境,研制了雾环境模拟舱,采用造雾器和净化器组合实现能见度10m到50km模拟。寻找模拟舱内空气均匀度监控方法,消除由空气不均匀带来的误差。测试不同型号的前向散射能见度仪和相同型号能见度仪,结果显示不同型号能见度仪测量值差别大于一倍,同一型号的能见度仪测量值相对误差在±5%内。尝试不同型号能见度仪修正方法,并且验证修正方法可行,修正后的不同型号仪器相对误差在±10%内。
        Visibility is an important element in meteorological,environmental and transport departments.The unified test environment and calibration standards have not been made for different visibility meters,which leads to great disparity in the results.For the unified environment,asimulation cabin has been developed.Visibility from 10 mto 50 km is simulated by fog generators and purifiers.A method has been put forward,which can eliminate the errors caused by the unevenness of air.Different models and the forward scattering visibility meters of the same model have been tested.The result shows that the difference in different models is greater than 100%.The relative error is within the range of±5%in the same type.A correction method has been developed,which will decrease the relative error within the range of±10%in different types.
