Air sampling was performed daily or twice daily in December 2014 (JARE-56), from December 2016 to March 2017 (JARE-58), and in December 2017 (JARE-59). These data are valuable for resolving daily variations in 7Be concentrations as they cover an extensive area of the Antarctic region for which there is currently little data. The data were collated in CSV format and are available from the National Institute of Polar Research (NIPR) at https://doi.org/10.17592/002.2022040392.
