A BASIC STUDY ON STANDARDIZATION OF THE SKY RADIANCE DISTRIBUTION

摘要

This research work aims to establish a standard of sky radiance distribution that covers various sky conditions. Data by continuous measurements were arranged according to solar altitude and further according to sky conditions sequentially from the clear sky to the overcast sky. This paper shows some examples of the sky radiance distribution graphically as a preliminary study on 'All sky model' of radiance distribution.
