"Diffuse radiation", on the other hand, describes the sunlight that has been scattered by molecules and particles in the atmosphere but that has still made it down to the surface of the earth.Direct radiation has a definite direction but diffuse radiation is just going any which way. Because...
Variation trend of direct and diffuse radiation in China over recent 50 years. Acta Physica Sinica, 60, 859-872. (in Chinese with English ab- stract) [马金玉, 梁宏, 罗勇, 李世奎 (2011). 中国近50 年太阳直接辐射和散射辐射变化趋势特征. 物理学报, 60, 859-872.]...
Direct radiation: It comes from the sun's disc and refers to radiation that is not dispersed in the atmosphere, and so has a fixed direction. The term “beam radiation” or “direct beam radiation” is also used to describe it. Diffuse radiation: The remainder of the radiation is spread ...
Definition of direct and diffuse radiation Description of direct and diffuse parts of global radiation Direct horizontal radiation (Bh) Shortwave radiation (0.2 - 3.0μm) arising from a narrow solid angle (5° aperture) centered around the sun's disk impinging on a horizontal surface. ...
The observed ηSTH values from the on-sun current density could be inflated from collecting the global solar radiation (i.e., both direct radiation and diffuse radiation) to power the PEC devices. Previous reports have shown that diffuse sunlight can be refracted and concentrated across optical ...
However the sparse distribution of data in space and time often leads to the use of modeled solar radiation for engineering applications. In this framework it is often desirable to deal with the separate direct and diffuse components of the solar radiation especially when errors of the order of ...

It is concluded that, with proper calibration and adequate attention to the effects caused by solar altitude, a temperature-compensated silicon-cell pyrheliometer can be used with confidence to measure direct, total, and diffuse solar radiation with an accuracy of at least ±3 percent. 展开 ...
The ratio between direct radiation on a tilted surface and direct radiation on a horizontal surface is examined on a daily and monthly average basis. This direct ratio factor, often called R b, is shown to vary with beam intensity. The atmospheric weighting model, presented in a previous paper...
