“…A large fraction of the studies dealing with solar radiation published during recent years have considered models of solar radiation (e.g., Quej et al ., 2016; Yao et al ., 2017; Jamil and Siddiqui, 2018; Antonopoulos et al ., 2019; Cao et al ., 2020), often focusing on the application of solar radiation calculations and forecasting with regard to photovoltaic (PV) power plants (e.g., Ghofrani et al ., 2016; Bouzgou and Gueymard, 2017; Eseye et al ., 2018; Srivastava et al ., 2019; Das, 2020). The global, direct, and diffuse radiation are commonly measured in the field (Marques Filho et al ., 2016; Gairaa et al ., 2017; Othman et al ., 2018; Chamorro et al ., 2020; Mohammad et al ., 2020). PAR is often measured in connection with its absorption by plants and transmittance through the canopy (Green et al ., 1995; Roujean, 1999; Gurrea‐Ysasi et al ., 2018; Gitelson et al ., 2019).…”
