Observational records have a key role when assessing long-term climate changes, though these are often influenced by residual non-climatic factors which may loosen their reliability to estimate the current state and evolution of the climate. In the frame of the Copernicus Climate Change Service (C3S), a novel approach, named RHARM (Radiosounding HARMonization), has been developed to provide a harmonized dataset of temperature, humidity and wind radiosounding profiles, along with an estimation of the uncertainties, for a substantial subset of radiosounding stations globally available. Decadal trends and anomalies, calculated at different latitudes and at global scale, will be shown and discussed.
