Relationship Between Sunshine Duration and Solar Radiation

open access: yesSolar Energy, 2013
Abstract This paper examines the relationship between sunshine duration and solar radiation received on the earth’s surface. Sixty-nine thousand pairs of sunshine–radiation readings from 670 sites were analyzed. A generalization of the Angstrom–Prescott equation of the form K ¯ = K ¯ clear [ β + ( 1 - β ) S γ

Generation of a Typical Meteorological Year Using Sunshine Duration Data

open access: yesEnergy, 2002
In this paper, we discuss the possibility of using the daily sunshine duration or the daily sunshine duration over day-length data instead of daily global solar radiation in order to develop a Typical Meteorological Year, TMY2, for localities with ...

Variability of Sunshine Duration in Western Ukraine

Scientific Herald of Chernivtsi University. Geography, 2023
The duration of sunshine is a crucial radiation characteristic of climate, serving as an indicator for both regional atmospheric circulation and surface atmospheric pollution variability. Ground observations using a heliograph, spanning a long duration, enable the detection of changes in the impact of climate-forming factors on modern warming.

Estimation of Sunshine Duration From the Global Irradiance Measured by a Photovoltaic Silicon Solar Cell

open access: yesRenewable and Sustainable Energy Reviews, 2014
Sunshine duration can be estimated using photovoltaic solar cells instead of conventional pyranometers or pyrheliometers, which are more expensive and therefore not suitable for low cost measurement applications in developing regions.
