This dataset was generated as part of the analysis conducted for the study by Kwon et al. (2020), Environmental Research Letters, “Recent weakening of the southern stratospheric polar vortex and its impact on the surface climate over Antarctica.”
This dataset provides the onset dates of Northern Hemisphere Stratospheric Polar Vortex (SPV) weakening events, identified using the same polar cap height (PCH) anomaly–based methodology applied in Kim & Choi (2024) and originally introduced by Kwon et al. (2020) for the Southern Hemisphere. By adopting the event definition used in Kim & Choi (2024), this dataset ensures full methodological consistency with recent SPV weakening research and enables robust hemispheric comparison of SPV variability.

This dataset was obtained during the research process of Kim and Choi (2024) and provides the onset dates of SPV weakening events, identified using the wind reversal method, which are commonly known as sudden stratospheric warming (SSW) events.

This dataset presents a new catalogue of active subglacial lakes beneath Thwaites Glacier, West Antarctica, identified using CryoSat-2 satellite radar altimetry. It details the boundaries, areas, and elevation changes of each lake, complete with 95% confidence intervals. The dataset also contains estimates of ice speed changes in the TG's grounding zone. For citation purposes, refer to the article by B-H Kim, C-K Lee*, K-W Seo, W S Lee, and J-W Park, 'New Catalogue of Thwaites Glacier Subglacial Lakes and Their Activity Revealed by CryoSat-2 Altimetry,' currently under revision for the Journal of Geophysical Research: Earth Surface.

This dataset consists of high-precision GNSS observation data collected from January to May 2025 at King Sejong Station, King George Island, Antarctica. The data can be used for monitoring crustal movements, surface stability, and glacial displacement in polar geophysical research.
The tidal observation equipment at the King Sejong Station in Antarctica was installed by the Korea Hydrographic and Oceanographic Agency in December 2019. The equipment measures tidal waves at 1-minute intervals by measuring changes in water pressure according to sea level height in harsh Antarctic environments such as sea ice.
