两种净全辐射测量方法的比较

Comparison with the two measurement methods of net radiation

净全辐射是研究地球热量收支状况的重要指标,我国目前使用的净全辐射表的测量准确度并不能满足需求。为了提高净全辐射测量的准确度,提出了利用四分量法测量净全辐射,在相同条件下对2种测量方法进行比对试验,通过比对实验数据的分析和研究,结果表明该方法有效的提高了净全辐射的精确度。

Net radiation is an important variable to study the earth heat fluxes. At present in China, the measurement accuracy of net pyrradiometer can not meet the demand. In order to improve that, this paper puts forward the method of using the four component algorithm. Under the same conditions of two measurement methods for comparison test, by comparing the data of the experiments and analysis, it shows that the four component method improves the measurement accuracy of net radiation effectively.
