Abstract：In order to promote the construction of meteorological automation,DFC1 type sunshine sensors have been installed at all stations in Jiangsu Province,and parallel observations of manual and automatic sunshine meters have been carried out from January 1,2019 to March 31,2020.By comparing the data during the parallel observation period at Xuzhou station,the differences between manual and automatic sunlight observation data are statistically analyzed,and the reasons for the differences are analyzed.The analysis results show that there is good consistency between manual and automatic sunshine observation data,ensuring the accuracy of data in automated business operations.The consistency of data in spring and winter is higher than that in summer and autumn;When the sunshine intensity is strong,the data difference is small,so the consistency between manual and automatic sunshine observation data is better at noon than during sunrise and sunset.In situations where the air quality is poor and there are clouds in the sky,there are significant differences in data.In response to this situation,an inversion model is established by utilizing the relationship between manual and automatic sunshine observation data,so that the two data can be converted to each other,which is conducive to improving the consistency and continuity of sunshine data in use and research analysis.
