Analysis of Hygroscopic Cloud Seeding Materials Using K-CPEC facility

This study presents the methodology and results of the chamber experiments conducted using the Korea Cloud Physics Experiment Chamber (K-CPEC) established by the Korea Meteorological Administration (KMA)/National Institute of Meteorological Sciences (NIMS) in South Korea. The research focused on warm clouds in South Korea, utilizing NaCl and CaCl₂, powder-type hygroscopic materials commonly used for cloud seeding experiments. The characteristics of these particles were measured, and their effects on cloud droplet growth were observed. Detailed descriptions of the aerosol and cloud chambers at K-CPEC, along with the experimental setup and measurement instruments, are provided. The methods outlined in this study can aid in the development and evaluation of new cloud-seeding materials, enhancing the effectiveness of cloud seeding techniques.
