Winter atmospheric boundary layer observations over sea ice in the coastal zone of the Bothnian Bay (Baltic Sea)
Presence of sea ice in the Bay of Bothnia affects the intensity of moisture and heat exchange between the atmosphere and the sea, and the radiation budget in the region. Depending on the sea ice extent it affects weather both locally and globally. The goal of Hailuoto Atmospheric Observations over S...

Presence of sea ice in the Bay of Bothnia affects the intensity of moisture and heat exchange between the atmosphere and the sea, and the radiation budget in the region. Depending on the sea ice extent it affects weather both locally and globally. The goal of Hailuoto Atmospheric Observations over Sea Ice (HAOS) campaign was to collect measurements of atmospheric boundary layer properties over the sea ice in the coastal zone west of the Hailuoto island (north-eastern Bay of Bothnia) and to increase our understanding of the processes at the interface of sea ice and air.
