Reflection and transmission of irradiance by snow and sea ice in the central Arctic Ocean in summer 2010
Reflection and transmission of irradiance by the combined snow and sea ice layer were measured at an ice camp (ca. 10 days) and several short-term stations (ca. 2 h) established in the western sector of the Arctic Ocean above 80°N during the 2010 summer. These measurements were made with an intentio...
