The project was conducted from 1998 to 2000 with a major field campaign involving [...] addressed the effects of clouds and of Arctic Haze on the radiative fluxes at the surface and in the atmospheric column for various states of the surface in the European Arctic. Major emphasis was put on convective [...] over the ice-free ocean and on stratiform clouds at low levels and their radiational exchange with sea ice. The effects of clouds on the radiative fluxes for various states of the ocean surface were studied

represents one of the most important connections between the Arctic Ocean and the North Atlantic. In the past few years, we’ve seen a major decline in Arctic sea ice in the region. In addition, more warm and salty [...] regional climate model for the Arctic. The model consists of several components: the atmosphere, sea ice, ocean and land. Simulations with this model help us interpret the Arctic climate, its variability and [...] climate changes in the Arctic are connected to the weather and climate in central Europe. The difficult thing about these interactions is the fact that, in addition to the Arctic factors, other aspects
