【摘要】 太阳辐射计是测量太阳直接辐射光谱特性的仪器,本仪器的设计特点是不仅能测量太阳直接辐射的光谱特性,还能测量太阳角散射(日晕)辐射特性。仪器在PC微机控制下,能自动对准和跟踪太阳,完成转换滤光片、调整增益、定时采集和存储数据等全部测量工作。现场实验表明所得大气光学厚度数据有较高的精度,甚至可以得到其变化情况。更多还原

【Abstract】 This solar photometer is designed to measure not only the spectral characteristics of direct solar radiation, but the angle scatterring property of the atmosphere (i.e. aureole). It is controlled by a microcomputer, so can work with functions of searching and tracking the Sun movement, converting niters, adjusting the gain of amplifier, sampling and storing the data on time. The experiments showed that the results measured are in high accuracy, even can obtain the variation of the atmospheric optical thickness.更多还原
