Acquisition methods for ultraviolet atmospheric transmittance at astronomical sites
Abstract
<p indent="0mm">Ultraviolet atmospheric transmittance is a key parameter inreflecting theoptical characteristics of the atmosphere in the ultraviolet region. It is practically significant in providing the basis for ground-based ultraviolet observation, especially in site surveys, telescope construction, and terminal equipment development. In this paper, common methods for obtaining ultraviolet atmospheric transmittance are introduced, including computational simulation and instrumental measurement, and their properties are compared and analyzed. Moreover, a new method, using the moon as a measuring object is proposed to acquire the ultraviolet atmospheric transmittance at night, and some suggestions are put forward.</p>
