Overview  
Title Antarctic surface air Beryllium-7 (Period-2:2020-2023)
Sub-Title
Data Summary Beryllium-7 concentrations in surface air samples collected at Syowa Station, Antarctica. The air sampling was conducted daily for three years from January 2020 to January 2023 under the Japanese Antarctic Research Expedition (JARE). In addition to this, it includes data from the "Shirase" sailing from the Pacific Ocean to the Southern Ocean from November to December 2021 and from the mobile observation from Syowa Station to Site H128 on the Antarctic ice sheet in 2022. These data are valuable for resolving daily variations in 7Be oncentration.
