Measurements include net radiation, turbulent heat fluxes, air temperature, humidity, and ancillary variables used to quantify local energy-exchange processes. Data were recorded continuously at a fixed instrumented mast following the procedures described in the associated publication. These observations support analyses of seasonal thaw dynamics and contribute to modelling soil-erosion susceptibility in High-Arctic environments.-105.92148569.230821Fonds de recherche du Québechttps://doi.org/10.13039/501100020951343526Caractérisation des signes avant-coureurs et des impacts de la dégradation du pergélisol sur les écosystèmes aquatiques dans un site du Haut Arctique
