紫外线和可见光（UV-VIS）辐射是大气层低边界层中稳定痕量气体光解和产生高活性原子和自由基的原因。大气中关键物种的光解频率取决于光谱分辨的光化通量。然而，到目前为止，直接测量和建模的光化通量和光解频率的相关物种的室内atmosis.In这项研究中，我们提出了系统的室内测量的光化通量和光解频率的亚硝酸（HONO），二氧化氮（NO2）和硝酸根（NO3）在夏季和冬季期间。将室内光化通量和光解频率的实验数据与对流层紫外可见光（TUV）模型获得的环境数据进行了比较。最后，运行一个建筑模型，通过该模型将积分光谱辐照度（UV-VIS）值与分光辐射计进行的测量值进行比较。测量与建筑模型的比较产生一个方程，该方程可以在将来用于预测在各种室内环境中的积分光谱光化通量值作为建筑参数的函数，例如建筑物的取向、玻璃窗的尺寸和厚度。(C)2016爱思唯尔有限公司版权所有
Ultraviolet and visible (UV-VIS) radiation is responsible for the photolysis of stable trace gases and production of highly reactive atoms and radicals in the lower boundary layer of the atmosphere. Photolysis frequencies of the key species in the atmosphere depend on the spectrally resolved actinic flux. However, to date direct measurements and modeling of the actinic flux and photolysis frequencies of species relevant for indoor atmospheres are scarce.In this study, we present systematic indoor measurements of actinic fluxes and photolysis frequencies of nitrous acid (HONO), nitrogen dioxide (NO2) and the nitrate radical (NO3) during summer and winter periods. The emerged experimental data of indoor actinic fluxes and the photolysis frequencies were compared to the ambient data obtained by the Tropospheric Ultraviolet and Visible (TUV) model. Finally, an architectural model was run by which integrated spectral irradiance (UV-VIS) values were compared to the measurements performed by the spectroradiometer. The comparison of the measurements with the architectural model yields an equation which can be used in the future to predict the integrated spectral actinic flux values in various indoor environments as a function of the architectural parameters such as orientation of the building, the size and the thickness of the glass windows.
