Abstract

The outline of the methods for processing raw data on daylight and solar radiation in Kitakyushu is introduced with examples in this paper. The data of Global illuminance, Direct normal solar illuminance, Global irradiance and Direct normal solar irradiance were gained at one-minute intervals continuously for twenty-four hours. Diffuse illuminance and Diffuse irradiance were calculated using four raw data. The processed data were summarized in the forms of daily/monthly averages and standard deviations with minimum and maximum values classified by half-hourly intervals.
