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。 The solar radiometer is a device that measures the direct solar spectral characteristics of the sun. The instrument is designed to measure not only the spectral characteristics of direct solar radiation but also the solar radiation (solar halo) radiation characteristics. The instrument under the control of the PC microcomputer, can automatically align and track the sun, complete the conversion filter, adjust the gain, timing acquisition and storage of data and other measurements. Field experiments show that the resulting optical thickness data of the atmosphere has higher accuracy and can even be changed.
