Webwas reported for different Arctic regions except the Summit station in Greenland where the cloud radiative forcing effect is positive the entire year due to the high surface albedo of the snow coverage (Miller et al.,2015,2024). The net cloud radiative forcing in the Arctic influences sea ice coverage and leads to more open water that in turn ... WebOct 26, 2024 · This work analyzes the occurrence of HOIC at Summit, Greenland, from July 2015 to June 2024. Using polarization lidar and ancillary atmospheric sensors, ice crystal orientations are identified and used to interpret cloud radiative impact on the surface radiation budget. We find HOIC occur in at least 25.6% of all ice-only column observations.
