As the planet is experiencing dramatic environmental problems mainly due to human activities, education plays an essential role in the formation of pupils’ attitudes toward the environment, both social and natural. That is, the depletion in the con

Plants require solar radiation for photosynthesis and their growth is directly related to the amount received, assuming that other environmental parameters are not limiting. Therefore, precise estimation of photosynthetically active radiation (PAR) i

In the photosynthesis process, solar radiation energy is converted to chemical energy by using atmospheric CO 2 . That is, almost all living species depend on energy produced through photosynthesis for their nourishing components thus making photosyn

The depletion in the concentration of ozone layer in the stratosphere may significantly increase the UV radiant flux levels (mainly the UVB, 280–315 nm) reaching the earth's surface. These modifications have raised concern among scientists and poli

This study explores the influence of air gaseous pollutants–aerosols and solar zenith angle (SZA) on the spectral diffuse-to-direct beam E dλ/E bλ irradiances ratio. It does so using ground-based spectroradiometric measurements taken over the Ath

The interrelationship between broadband solar components, global (RS) and diffuse (Rd) and the photosynthetic photon flux density components, global (QP) and diffuse (QPd), is investigated using a 2-year data archive obtained at Athens, Greece. These

In this paper, simple Artificial Neural Network (ANN) models for estimating daily solar global broadband as well as solar spectral global UV and PAR radiant fluxes have been established. The data used in this analysis are global ultraviolet UV (G UV

Proper design and performance predictions of solar energy systems require accurate information on the availability of solar radiation. The diffuse-to-global solar radiation correlation, originally developed by Liu and Jordan, has been extensively use

The influence of the atmospheric turbidity on the spectral distribution of solar irradiance components is investigated using ground-based spectroradiometric measurements taken in Athens area during May 1995. It is found that both the diffuse-to-globa
