WebThis budget includes radiative, turbulent, and ground heat fluxes, and ultimately controls the evolution of surface temperature. At Summit Station, clouds radiatively warm the surface in all months with an annual average cloud radiative forcing value of 33 W m−², largely driven by the occurrence of liquid-bearing clouds. The magnitude of the ... WebAug 1, 2024 · The Summit observatory is located at 3215 m above mean sea level (MSL) at the top of the Greenland Ice Sheet (72.6°N, 38.5°W). Cloud and atmospheric parameters are measured by remote sensing instruments, complemented by …
Radiative Influence of Horizontally Oriented Ice Crystals …
WebData collected by multiple projects are leveraged to calculate all surface energy budget (SEB) terms at Summit, Greenland, for the full annual cycle from July 2013 to June 2014 and extend to longer periods for the radiative and turbulent SEB terms. Radiative fluxes are measured directly by a suite of broadband radiometers. WebAt Summit Station, clouds radiatively warm the surface in all months with an annual average cloud radiative forcing value of 33 Wm2, largely driven by the occurrence of … cherna lubov bg audio

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. WebSep 12, 2024 · The results describe in detail how southerly, northerly, and zonal circulation regimes impact observations at Summit Station, Greenland. This southerly regime is linked to large anomalous... flights from lax to bergen norway
