Abstract: Recently analyzed satellite-derived global precipitation datasets from 1987 to 2006 indicate an increase in global-mean precipitation of 1.1%?1.4% decade?1. This trend corresponds to a hydrological sensitivity (HS) of 7% ...

Abstract: The observations of solar irradiance at the surface, total cloud cover, and precipitation rates have been used to evaluate aerosol?cloud interactions in a GCM. Records from Germany and the United States were available for ...

Abstract: A statistically significant decrease in mean annual global solar radiation between 1964 and 1990 under completely overcast skies was found at five out of eight studied locations in Germany. A decrease of global solar ...

Abstract: In a series of equilibrium experiments the climate response to present-day radiative forcings of anthropogenic greenhouse gases and aerosol particles is calculated. The study was performed with a model system consisting ...

Abstract: The impact of Arctic sea ice concentrations, surface albedo, cloud fraction, and cloud ice and liquid water paths on the surface shortwave (SW) radiation budget is analyzed in the twentieth-century simulations of three ...

Abstract: bservations have revealed strong variability of shortwave (SW) irradiance at Earth?s surface on decadal time scales, referred to as global dimming and brightening. Previous studies have attributed the dimming and brightening ...
