Variability and properties of liquid-dominated clouds over the ice-free and sea-ice-covered Arctic Ocean
Due to their potential to either warm or cool the surface, liquid-phase clouds and their interaction with the ice-free and sea-ice-covered ocean largely determine the energy budget and surface temperature in the Arctic. Here, we use airborne measurements of solar spectral cloud reflectivity obtained...
