摘　　要：为了分析两种不同仪器的观测差异,文章对东胜国家基本气象站2018年10月~2019年2月的暗筒式日照计与DFC2型光电式数字日照计观测记录进行对比分析。文章分析了人工观测与自动观测记录中的小时日照时数相同时次的占比和一致性,以及两者逐日日照时数平均差值、逐月日照时数差值。总结出人工观测日、月累计日照总时数小于自动观测值,自动观测仪器具有灵敏度高、时间分辨力高等明显优势。To analyze the difference in observation between the two instruments,this paper makes a comparative analysis of observation data between dark-tube sunshine recorder and DFC2 photoelectric digital sunshine recorder of Dongsheng national basic meteorological station from October 2018 to February 2019.The proportion and consistency of sunshine duration in manual observation and automatic observation are analyzed.And the average difference of daily sunshine hours and monthly sunshine hours are also described.It is concluded that the total hours of sunshine in manual observation days and months are less than that in automatic observation.The automatic observation instrument has obvious advantages of high sensitivity and high time resolution.
