A novel pyrheliometer with high accuracy 一种新型的高精度太阳直射仪
Two kinds of methods are used to calculate the aerosol optical depths of wide-band from the direct solar irradiation detected by pyrheliometer on the ground under the condition of cloud free sky. The results are obtained to be similar. 利用晴空无云条件下地面上实测的太阳直接辐射资料,用两种不同的方法反演了宽频上的气溶胶光学厚度,得到了比较一致的结果。
