Abstract: Using the parallel observation data of sunshine duration from 156 national stations in Sichuan province from January to March 2019, this paper compared and evaluated the consistency between automatic and artificial observations of sunshine duration and the consistency between artificial and automatic sunshine duration at different levels of sunshine duration. The results show that most stations have slightly more artificial sunshine duration than automatic sunshine duration. Stations with positive mean error and larger root mean square error and lower hourly correlation coefficients almost all appeared in basin areas. In areas with sufficient sunshine, such as Pangzhihua, Liangshan, Ganzi and Aba (hereinafter referred to as Panzhihua Sanzhou), artificial sunshine duration is closer to automatic sunshine duration compared with rainy basins. Artificial sunshine duration of stations in Panzhihua Sanzhou are more accurate in longer sunshine duration level. Artificial sunshine duration of stations in Basin are the opposite. When the automatic sunshine duration is greater than 8h, the artificial sunshine duration of most stations are slightly smaller than automatic sunshine duration, the error between them is smaller, and the correlation is higher. When it is less than 8h, the artificial sunshine duration of most stations are larger than the automatic sunshine duration. When the automatic sunshine duration lays between 2-8h, the artificial sunshine duration of most stations have the largest error and the worst correlation with automatic sunshine duration.
