Black carbon (BC) concentrations were measured to investigate the filter spot loading effect in raw BC data at 5-minute time-based resolution using a Dual-wavelength(BC 880nm, UV 370nm). Measurement of optically-absorbing Black Carbon particles in Arctic-Antarctic Ocean.
Condensation particle counter measures the number of aerosol condensation particles of > 10nm in diameter for CPC3772 and >2.5nm for CPC3776. To study aerosol formation and growth in Arctic-Antarctic Ocean.
Aerosol scattering coefficients for three different wavelengths (λ=450, 550, and 700nm) are measured almost continuously by a nephelometer in the Antarctic ocean. To determine the optical properties of aerosols in the Antarctic ocean.
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.
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 provides the onset dates of major Northern Hemisphere Sudden Stratospheric Warming (SSW) events, objectively classified into three types: Displacement–Displacement (DD), Displacement–Split (DS), and Split–Split (SS). The classification follows the wave–amplitude–based methodology introduced by Choi et al. (2019), which uses geopotential height at 10 hPa averaged over 55–65°N to determine the dominant planetary–wave structure associated with each event. For each SSW event, the central date is converted to a standard calendar date (Year–Month–Day) and Day of Year (DOY). The NASA MERRA reanalysis is used to identify and classify SSW events for the period 1979–2014. This dataset can be used for studies of stratosphere–troposphere coupling, polar vortex variability, wintertime climate dynamics, and climate-model evaluation. The dataset is associated with the study published in Choi et al. (2019), DOI: 10.1175/JCLI-D-18-0223.1.
