光电式数字日照计观测应用与评估

Application and evaluation of photoelectric digital sunshine recorder observation

文章利用2019年1~6月北京地区国家级气象站光电式数字日照计和暗筒式日照计的平行观测数据,根据两种日照计的工作原理,通过绝对偏差、相对偏差、月极值检验、数据一致性等参数对日照计进行了对比评估。依据评估结果分析了观测设备的差异性,总结出两种日照计观测过程的优缺点,为实现自动化观测数据的准确性提供参考。

By using the parallel observation data of photoelectric digital sunshine recorder and dark-tube sunshine recorder of national meteorological station in Beijing from January to June in 2019,based on the principle of two kinds of sunshine recorder,this paper compares and evaluates the sunshine recorders through the absolute deviation,relative deviation,monthly extreme value test,data consistency and other parameters.According to the evaluation results,the differences of observation equipment are analyzed.The advantages and disadvantages of two kinds of sunshine recorder observation processes are summarized to provide reference for realizing the accuracy of automatic observation data.
