Regular balloon-borne cryogenic frostpoint hygrometer observations were conducted at Syowa Station, Antarctica, from 2013 to 2022 to monitor long-term variations in water vapor concentration in the upper troposphere and lower stratosphere over Antarctica. The data was screened and published in Ascii format for research purposes. This is the only regular balloon-borne hygrometer observation in the Antarctic region and is expected to be used for various purposes, such as climate change monitoring, research on water vapor transport processes, and validation of satellite observations.
