In recent years, solar blind ultraviolet detection has been widely used in power fault detection. Based on atmospheric temperature profile and MODTRAN, we conduct simulation analysis on the influence of atmospheric temperature on solar blind ultraviolet atmospheric transmission. And finally the relationship between atmospheric temperature and ultraviolet atmospheric transmission was obtained through wavelength analysis and curve fitting. Based on the simulation relational expression, the quantitative analysis of atmospheric temperature and atmospheric transmission can be carried out, which can promote the study of the characteristics of solar blind ultraviolet transmission in the atmosphere and improve the accuracy of corona detection.
