Concentrations of condensation nuclei (CN) with diameters larger than 10 nm and 7 nm have been measured using condensation particle counters at Syowa Station, Antarctica during the periods of May 1997 – January 2017 and January 2014 – December 2021, respectively. Herein, we present long-term CN records obtained at Syowa Stations. Data including local contamination and errors were screened for scientific usage. The daily mean and hourly mean CN data after the screening are provided.
