The characteristics of atmospheric ice nuclei measured at the top of Huangshan (the Yellow Mountains) in Southeast China using a newly built static vacuum water vapor diffusion chamber

Atmospheric ice nuclei (IN) concentrations at the top of Huangshan (Yellow Mountains), China, exhibit strong correlations with coarse aerosol particles (0.5–20 μm in diameter) and show significant diurnal variation, peaking at 14:00 LST. Researchers measured IN concentrations between −15 °C and −23 °C using a newly built static vacuum water vapor diffusion chamber, finding average concentrations ranging from 0.27 to 7.02 L⁻¹. The study revealed that coarse particles (R² > 0.60) are far more influential than smaller particles (R² = 0.10), with IN levels aligning closely with aerosol particle fluctuations. A parametric equation was developed to model IN variations based on temperature and supersaturation, offering new insights into atmospheric ice nucleation processes in mountainous regions.
