北京地面紫外辐射(光谱)的观测与分析

MEASUREMENTS AND ANALYSES ON BEIJING GROUND SURFACE ULTRAVIOLET RADIATION(SPECTRUM)

通过对北京大气物理研究所与长春光机所合作研制的地基太阳紫外辐射光谱仪观测资料的分析 ,和用辐射传输模式UVSS计算的结果 ,对影响到达地面的UVB辐照度的主要因子太阳高度角 (SZA)、臭氧总量和地表反照率进行了分析研究。最后对紫外光谱仪的观测资料做了总量和谱分析。

Based on some analyses on spectral irradiance measured with the Sun-Atmosphere Ultraviolet Spectrum Radiometer (SAUVS) developed by the Institute of Atmospheric Physics, Chinese Academy of Sciences, Beijing and the results calculated by means of radiative transfer models UVSS, the influences of various important factors affecting UV irradiance reaching the ground surface, such as solar zenith angle(SZA), ozone column amount and ground surface albedo were evaluated. Then total amount and spectral analyses were made on data of ultraviolet spectroradiometer.
