摘要
为了研究暗筒式日照计与自动日照计数据间的差值关系,文章通过分析长春国家基准气候站2020年1月至2022年12月DFC2型光电式数字日照计和暗筒式日照计获取的数据,进行月、季、年的比较。结果表明:1—3月DFC2型光电式数字日照计数据大于暗筒式日照计,4—9月暗筒式日照计数据大于DFC2型光电式数字日照计,10—12月两者数值相差较小;夏季DFC2型光电式数字日照计数据明显小于暗筒式日照计数据,冬季DFC2型光电式数字日照计数据大于暗筒式日照计数据。在使用月、年日照时数数据进行气候分析时,应注意不同仪器的差异,并进行数据偏差订正。
In order to study the difference between the data of the dark tube sunshine meter and the automatic sunshine meter,the article analyzed the data obtained from the DFC2 photoelectric digital sunshine meter and the dark tube sunshine meter at the Changchun National Reference Climate Station from January 2020 to December 2022,and compared on a monthly,quarterly,and yearly basis.The results showed that from January to March,the DFC2 photoelectric digital sunshine meter was greater than that of the dark tube sunshine meter,and from April to September,the dark tube sunshine meter was greater than that of the DFC2 photoelectric digital sunshine meter,and from October to December,the difference between the two values was relatively small.The data of DFC2 photoelectric digital sunshine meter in summer is significantly smaller than that of dark tube sunshine meter,and in winter,the data of DFC2 photoelectric digital sunshine meter is larger than that of dark tube sunshine meter.When using monthly and annual sunshine hours data for climate analysis,attention should be paid to the differences between different instruments and data bias correction should be carried out.
