Influence of synoptic weather patterns on solar irradiance variability in northern Europe
Parding, Kajsa; Liepert, Beate G.; Hinkelman, Laura M.; Ackerman, Thomas P.; Dagestad, Knut-Frode; Olseth, Jan Asle (Peer reviewed; Journal article, 2016-05)Observations 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 ... -
Shortwave absorptance in a tropical cloudy atmosphere: Reconciling calculations and observations
Parding, Kajsa; Hinkelman, Laura M.; Ackerman, Thomas P.; McFarlane, Sally A. (Peer reviewed; Journal article, 2011-10-04)[1] The absorption of shortwave (SW) radiation by clouds is a topic surrounded by contradictory reports and controversy. Some studies have shown large discrepancies between observed SW absorption and absorption predicted ...
