Both daylighting simulation tools and daylight availability data for various weather conditions are essential to design an architecture with energy efficiency and luminous environment of good quality. Though there are useful daylighting simulation tools being developed in the world, daylight source models are insufficient for the needs for both research and practice. Existing databases and numerical models on solar radiation and daylight availability are usually based on the measured data by surface observations at the limited number of meteorological observatories and daylighting measurement stations. Because of the financial difficulty to set up and operate such a station, the solar radiation and daylight availability data incline to the cities and countries where national meteorological observatories or major research institutes are located.As the alternative approaches of surface observations, the author proposed a statistical model for global and beam solar radiation using the ima … More ges of Japanese geostational meteorological satellite GMS-5. The model is based on the multiple linear regression analysis to estimate surface observed hourly cumulative global and beam radiation values from the satellite observed image values. The major difference of the model and the traditional satellite-derived models is that it utilizes the three channels of meteorological satellite images. The visual channel, the only one used in the traditional method, is converted to the albedo representing the optical thickness of cloud. The infrared channel corresponds to the height of cloud deck. The water vapor channel approximates the relative humidity of the troposphere. The combination of three channels has been expected to provide more detailed information on the atmosphere than ever.The purpose of the project is to develop the Quasi-realtime Daylight Source Model based on Geostational Meteorological Satellite Images. First, it examines the precision of a statistical model to estimate global and beam irradiance and illuminance at hourly intervals by the three channels of the geostational meteorological satellites images. The multiple liner regression analysis is performed between the satellites image values and instantaneous illuminance and irradiance measured at the Fukuyama University. By the weather condition analysis, causes reducing the precision are studied. The daylight source model is applied to estimate the geographical distribution of daylight availability. Less

日光模拟工具和各种天气条件下的日光可用性数据对于设计具有高能效和高质量光环境的建筑至关重要。虽然目前国际上已经有了一些实用的日光照明模拟工具，但日光光源模型还不足以满足研究和实践的需要。现有的关于太阳辐射和日光可用性的数据库和数值模型通常基于数量有限的气象观测站和日光测量站的地面观测数据。由于建立和运行这样一个站的财政困难，太阳辐射和日光可用性数据倾向于国家气象台或主要研究机构所在的城市和国家。作为地面观测的替代方法，作者提出了一个利用图像的全球和射束太阳辐射统计模型。 ...更多信息 日本气象卫星GMS-5。该模型是基于多元线性回归分析，以估计地面观测的每小时累积的全球和波束辐射值的卫星观测图像值。该模型与传统的卫星遥感模型的主要区别在于它利用了三个通道的气象卫星图像。将传统方法中唯一使用的可见光通道转换为代表云光学厚度的可见光通道。红外通道对应于云顶高度。水汽通道近似于对流层的相对湿度。三个通道的组合有望提供比以往更详细的大气信息。该项目的目的是开发基于地球物理学气象卫星图像的准实时日光源模式。首先，它检查了一个统计模型的精度，以估计全球和光束的辐照度和照度在每小时间隔的三个通道的地球物理气象卫星图像。对福山大学的瞬时照度和辐照度与卫星图像值进行了多元线性回归分析。通过对气象条件的分析，研究了影响精度的原因。日光源模型被应用于估计日光可用性的地理分布。少
