Calculated the diffuse and direct parts of global solar radiation in Baghdad city for the period (1983-2005) depending on clearness index by applying the two world models of Liu -Jordan

Iraqi Journal of Physics, 2019
In this paper solar radiation was studied over a region of Baghdad (Latitude 33.3o and longitude 44.4o). The two parts of global solar radiation: diffuse and direct solar radiation were estimated depending on the clearance index of measured data ...

Estimation of global solar radiation in Venezuela

, 2008
Una nueva relación entre la duración de la insolación y la radiación solar global se estudia a través del análisis de datos de radiación solar global y horas de sol de once estaciones meteorológicas de Venezuela en el período 1964-1993. Se usó el método de la regresión lineal para estimar la ecuación de Angström-Prescott.

Solar Radiation Transfer Through a Subarctic Shrub Canopy [PDF]

, 2007
Much of the low Arctic is covered with shrubs that are partially buried by snow in winter and become exposed during melt. This study presents measurements and modeling of shortwave radiation reflection and extinction by a deciduous shrub canopy emerging ...

Heliotropic dust rings for Earth climate engineering [PDF]

, 2013
This paper examines the concept of a Sun-pointing elliptical Earth ring comprised of dust grains to offset global warming. A new family of non-Keplerian periodic orbits, under the effects of solar radiation pressure and the Earth's J(2) oblateness ...

Temporal Evolution, Oscillation and Coherence Characteristics Analysis of Global Solar Radiation Distribution in Major Cities in China’s Solar-Energy-Available Region Based on Continuous Wavelet Transform

Applied Sciences
The majority of the energy required for human survival is derived either directly or indirectly from solar radiation, thus it is important to investigate the periodic fluctuations in global solar radiation over time.

Improvement global solar radiation estimation

IET Renewable Power Generation, 2017
Energy yields of photovoltaic power plants are directly related to the availability of the global solar radiation (GHI). An accurate performance analysis of these power plants depends strongly on the quality and the reliability of the solar resource assessment. This study proposed to improve the accuracy of the GHI database provided by satellites.

The potential of global solar radiation in the Silesia region as a renewable source of energy

Environmental & Socio-economic Studies, 2016
Historically, Silesia has been at the centre of the Polish coal industry for many years and thus has experienced poorer air quality compared to other voivodeships.
