A New Index Assessing the Viability of PAR Application Projects Used to Validate PAR Models
Agronomy, 2021 Photosynthetically active radiation (PAR) is a useful variable to estimate the growth of biomass or microalgae. However, it is not always feasible to access PAR measurements; in this work, two sets of nine hourly PAR models were developed.

Effects of Air Pollution on Sunshine Duration Trends in Typical Chinese Cities
Atmosphere, 2022 Long-term trends in sunshine duration in Chinese cities have been closely linked to factors caused by air pollution. To understand this impact on sunshine duration (SD), surface solar radiation from 1981 to 2020, annual PM2.5 concentration from 2012 to ...

A Change of Yearly Atmospheric Clearness Index in Korea [PDF]
Journal of the Korean Solar Energy Society, 2011 Since the atmospheric clearness index is main factor for evaluating atmosphere environment, it is necessary to estimate its characteristics all over the major cities in Korea. We have begun collecting clearness index data since 1982 at 16 different cities and considerable effort has been made for constructing a standard value from measured data at each

Modeling of Daily Global Solar Irradiation in Timisoara by Using a Fuzzy Approach
Annals of West University of Timisoara: Physics, 2018 This paper proposes a new simple model to forecast daily global solar irradiation one day ahead using the Takagi-Sugeno fuzzy methods. The model is based on solar radiation data measured in Timisoara, Romania.
