This dataset contains measurements of migration rates, orientations, and morphometric parameters of snow barchan dunes located approximately 800 m from Concordia Station, East Antarctica. The measurements were performed on orthorectified near-infrared time-lapse images acquired between 2017 and 2022. Image acquisition was limited to periods with sufficient daylight, typically between August and March of each year. The effective monitored surface area with adequate spatial resolution to clearly distinguish dune features is approximately 5200 m². The dataset includes the event name (Combined), migration rate of individual barchans (speed(m/h) [m h⁻¹], migration orientation measured counterclockwise from geographic north (orientation_migration), dune crest orientation using the same angular convention (orientation), total dune length (Ltot) [m], total dune width perpendicular to the main axis (width_perp) [m], right horn length (Lh1) [m], left horn length (Lh2) [m], and the acquisition date and time of the image used for measurement (UTC). Migration rates were derived from sequential image analysis. The observations were collected as part of a long-term study of snow surface evolution aimed at quantifying the role of snow in Antarctica climate. The primary purpose of this dataset is to provide standardized quantitative descriptors of snow barchan migration and geometry for use in studies of surface processes, wind-driven sediment transport, and landscape evolution in polar environments. Data were generated through systematic image processing and morphometric extraction applied to time-series near-infrared imagery collected at the study site.
