Recent Data

  1. ASI Algorithm Daily AMSR2 (AND AMSR-E) Antarctic Sea ice Concentration 2015

    These sea ice concentration data are retrieved with the ARTIST Sea Ice (ASI) algorithm (Spreen et al., 2008) which is applied to microwave radiometer data of the sensors AMSR-E (Advanced Microwave Scanning Radiometer for EOS) on the NASA satellite Aqua, and AMSR2 (Advanced Microwave Scanning Radiometer 2) on the JAXA satellite GCOM-W1. The ASI algorithm using AMSR-E data was first implemented at IUP in 2002 and has been continuously producing sea ice concentration data since then. As several details of the processing chain have changed over the years, in 2018, all ASI ice concentration data for the Arctic and Antarctic based on AMSR-E and AMSR2 were reprocessed with exactly the same parameters, settings and software. The result are ASI data, version 5.4. The details are explained in the following sections.

Popular Data

  1. GNSSS data of King Sejong Station, 2025

    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.

  2. New Catalogue of Thwaites Glacier Subglacial Lakes and Their Activity Revealed by CryoSat-2 Altimetry

    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.

  3. Tidal variation observation of the King Sejong Station, Antarctica in 2025

    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.
