Abstract:

This dataset contains high-frequency surface meteorological and surface-energy-balance observations collected in Cambridge Bay, Nunavut, Canada, during 2023. 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.
