The collection of accurate spectra in the field requires an awareness of the influences of the various sources of illumination, atmospheric characteristics and stability, winds, instrument field of view, target viewing and illumination geometry, instrument scanning time, and the spatial and temporal variability of the characteristics.

In this paper,by using the international atmospheric transmission simulation package LOWTRAN,the atmospheric ultraviolet transmission under varying conditions of geographical locations,heights above sea level,visibility,directions of light pathways and the transmission ranges are analyzed,and the simulation results thus obtained not only can basically exe.
