摘要
利用国际上知名软件LOWTRAN7,分别计算晴空时总日射和散射条件下辐照度与光照度之间的定量关系,得到不同大气能见度和太阳高度对其影响规律。同时发现,光合有效辐射波段的总日射辐照度和散射辐照度与光照度的关系是线性的,而全波段的总日射辐照度和散射辐照度与光照度的关系是非线性的。计算结果与Brown的测量结果相当接近。
By using the software LOWTRAN 7,the quantitative relationship between irradiance and illuminance for global radiation and scattering radiation under cloudless sky are calculated respectively.The results show that the effects of atmospheric visibility and solar altitude on the quantitative relationahip are regular,and the relationship between irradiance and illuminance for globai solar irradiance and scattering irradiance at the wave range of photosynthetically active radiation(PIR)is linear,whereas the relationship at total wave range is nonlinear.By comparison with the measurements of Brown,the calculated results are closely to the measurement data.Therefore,the calculated results are valid.
