Global Solar Radiation Transfer and Its Loss in the Atmosphere

Polarized Radiative Transfer in Solar Atmosphere

The observations indicate the existence of linear polarization in the hydrogen Hα spectral line observed during the solar flare events. This emission of polarized radiation is of the order of 5% and is usually explained as a consequence of collisions of hydrogen atoms with the beam of fast protons coming from coronal regions. This article presents a brief overview of the recent solar flare pola...

A Comparative Study of the Available Measured Global Solar Radiation in Iraq

                                                                 In Iraq, solar radiation field measurements are available only for very limited locations such as some universities and research centers. This article reviews and compares the measured monthly averaged global solar radiation data for Iraqi provinces and cities available in the literature and studies over the internet especially Go...
