Global Warming and Local Dimming: The Statistical Evidence [PDF]
Journal of the American Statistical Association, 2011 Two effects largely determine global warming: the well-known greenhouse effect and the less well-known solar radiation effect. An increase in concentrations of carbon dioxide and other greenhouse gases contributes to global warming: the greenhouse effect. In addition, small particles, called aerosols, reflect and absorb sunlight in the atmosphere. More

Global dimming or local dimming?: Effect of urbanization on sunlight availability [PDF]
Geophysical Research Letters, 2005 From the 1950s to the 1980s, a significant decrease of surface solar radiation has been observed at different locations throughout the world. Here we show that this phenomenon, widely termed global dimming, is dominated by the large urban sites. The global‐scale analysis of year‐to‐year variations of solar radiation fluxes shows a decline of 0.41 W/m2 ...

Is global dimming and brightening in Japan limited to urban areas? [PDF]
Atmospheric Chemistry and Physics, 2016 Worldwide observations indicate secular trends of all-sky surface solar radiation on a decadal time scale, termed global dimming and brightening. Accordingly, the observed surface radiation in Japan generally shows a strong decline until the end of the

Image dependent energy-constrained local backlight dimming [PDF]
2012 19th IEEE International Conference on Image Processing, 2012 In this work, we consider and propose two extensions to an optimization-based image dependent backlight dimming algorithm. The first extension introduces error weighting based on human perception of luminance, aiming to improve the perceived image quality; the second extension adds an adjustable term for power consumption to the cost function, allowing
