<!--!introduction!--> Determination of shortwave (SW) and longwave (LW) radiation from space is fundamental in regions where few surface observations are available. In the Arctic this is particularly important due to the complex feedback mechanisms affecting climate in this region. Few sites located in the Arctic region provide surface radiation flux (SRF) measurements long enough to conduct systematic comparisons with satellite products capturing the seasonality of atmospheric and surface parameters. Long-term measurements of downward and upward SW (DSI and USI) and LW irradiances (DLI and ULI) are carried out at the Thule High Arctic Atmospheric Observatory (THAAO, 76.5° N, 68.8° W, https://www.thuleatmos-it.it), in North-Western Greenland. DSI and DLI measurements were started in 2009, and USI and ULI in 2016. In this analysis the four SRF components have been compared with monthly and daily Level 3 Clouds and the Earth’s Radiant Energy System (CERES) surface products , with the aiming of assessing ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ...
