摘要
文章利用云南省125个国家地面观测站2019年4—6月平行观测期间暗筒式日照计(人工观测)和DFC2型光电式数字日照计(自动观测)日照资料,1991—2020年历年日照数据以及2020年光电式数字日照计自动观测日照资料,探究了平行观测期间数据的一致性,分析了2020年自动观测日照时数月、年总量以及数据异常偏高的原因。所得结果以期为气候分析、资源开发等提供准确的日照数据,同时为更好地推进气象现代化提供参考。
Based on the sunlight data of the dark-tube sunlight recorder(manual observation)and DFC2 photoelectric digital sunlight recorder(automatic observation)during the parallel observation period from April to June in 2019,and by using the sunshine data of calendar years from 1991 to 2020 and automatic observation sunshine data of photoelectric digital sunshine meter in 2020,this paper explores the consistency of data during parallel observation.The monthly and annual total sunshine hours automatically observed in 2020 as well as the reasons for the unusually high data are analyzed.The results are expected to provide accurate sunshine data for climate analysis and resource development,and provide reference for better promoting meteorological modernization.
