Clouds and radiation processes in regional climate models evaluated using observations over the ice-free Arctic Ocean
peer reviewed The presence of clouds in the Arctic regulates the surface energy budget (SEB) over the sea‐ice surface and the ice‐free ocean. Following several previous field campaigns, the cloud–radiation relationship, including cloud vertical structure and phase, has been elucidated; however, mode...

peer reviewed The presence of clouds in the Arctic regulates the surface energy budget (SEB) over the sea‐ice surface and the ice‐free ocean.
