This dataset reports raw half-hourly radiative fluxes acquired at site D17 on the marginal slopes of Adelie Land (East Antarctica) and complements another dataset on near-surface meteorological variables including drifting-snow mass fluxes at the same location. The available data have been measured almost continuously since mid February 2014 with a Kipp and Zonen CNR4 net radiometer installed 2 m above ground and include downward/upward shortwave/longwave radiation. Latitude: 66.7°S ; Longitude 139.9°E Date/Time (UTC): Start:2014-02-18 06:00 ; End: 2019-12-07 23:30 Elevation 450 m The data files contain the following variables and units: YYYY: year; MM: month; DD: day; hh: hour; mm: minute; SWU: upward shortwave radiation (W m-2); SWD: downward shortwave radiation (W m-2); LWU: upward longwave radiation (W m-2); LWD: downward longwave radiation (W m-2);
