Volcanic aerosols from the 1991 Mount Pinatubo eruption greatly increased diffuse radiation worldwide for the following 2 years. We estimated that this increase in diffuse radiation alone enhanced noontime photosynthesis of a deciduous forest by 23% in 1992 and 8% in 1993 under cloudless conditions. This finding indicates that the aerosol-induced increase in diffuse radiation by the volcano enh...

conclusions a long-term longitudinal study encompassing integrated research is needed to fully understand the traumatic experiences of caregivers. unless research on tbi or dai trauma is given its proper attention, the burden of trauma and injury on societies will continue to exacerbate globally. context as with care giving and rehabilitation in chronic illnesses, the concern with traumatic bra...

mineral dust is produced from both natural and anthropogenic sources. dust aerosols can be transported over long distances in the atmosphere. they reduce the incident shortwave radiation to the surface by absorbing and scattering the solar radiation; thereby leading to a cooling effect at the surface and lower tropospheric temperature. on the other hand, by absorption and re-emission of longwav...

The optimum design of solar energy systems strongly depends on the accuracy of  solar radiation data. However, the availability of accurate solar radiation data is undermined by the high cost of measuring equipment or non-functional ones. This study developed a feed-forward backpropagation artificial neural network model for prediction of global solar radiation in Makurdi, Nigeria (7.7322  N lo...

For analyzing cooling loads, day-lighting, and building-integrated photovoltaic (BIPV) systems, solar radiation daylight illuminance data are required. However, these sparse. Furthermore, studies have shown that the energy potential of systems for entire building skin (BS) unconventional orientations, such as east, west, north need further exploration. Thus, this study presents findings from me...
