Editorial for the Special Issue “Solar Radiation, Modeling, and Remote Sensing”

open access: yesRemote Sensing, 2019
Surface-solar radiation is of vital importance for life on Earth, radiation−energy balance, photosynthesis, and photochemical reactions, meteorological and climatic conditions, and the water cycle.

Solar Radiation Transfer Through a Subarctic Shrub Canopy [PDF]

open access: yes, 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 ...

Solar Radiation Parameters for Assessing Temperature Distributions on Bridge Cross-Sections

open access: yesApplied Sciences, 2018
Solar radiation is one of the most important factors influencing the temperature distribution on bridge girder cross-sections. The bridge temperature distribution can be estimated using estimation models that incorporate solar radiation data; however ...

Mapping of solar energy potential in Fiji using an artificial neural network approach

open access: yesHeliyon, 2022
The concerned stakeholders have been pursuing renewable energy seriously due to its overwhelming benefits. Countries that receive less solar radiation are not lagging behind as they are working to optimize the available radiation let alone of countries ...

Orbital dynamics of earth-orbiting 'smart dust' spacecraft under the effects of solar radiation pressure and aerodynamic drag [PDF]

open access: yes, 2010
This paper investigates how the perturbations due to asymmetric solar radiation pressure, in presence of Earth's shadow, and atmospheric drag can be balanced to obtain long-lived Earth centered orbits for swarms of SpaceChips, without the use of active ...

Angström-Prescott empirical model to estimate solar radiation in Norte de Santander, Colombia

open access: yesRevista de Investigación, Desarrollo e Innovación, 2021
The document shows the application of the empirical Angström-Prescott model in different places in Norte de Santander, Colombia. The model estimates solar radiation from hours of sunlight, at a site where brightness and solar radiation are measured.

Solar Radiation Maps

open access: yes, 2018
Solar maps are very interesting tools to describe the characteristics of a region from the solar radiation point of view, and can be applied in atmospheric sciences and for energy engineering. To make them possible, a solar radiation numerical model is proposed. This one allows us to estimate radiation values on any point on earth. The model takes into

An oriented-design simplified model for the efficiency of a flat plate solar air collector [PDF]

open access: yes, 2010
In systems design, suitably adapted physical models are required. Different modelling approaches for a solar air collector were studied in this paper. First, a classical model was produced, based on a linearization of the conservation of energy equations.
