The influence of the atmospheric low-pressure core on the ground-based ice-nucleation particle abundance in the North Slope of Alaska: A preliminary report
This is a poster presentation providing a visual representation of the research through text, charts, graphs. Mixed-phase clouds (MPCs), which contain both ice crystals and supercooled liquid droplets, are ubiquitous over the North Slope of Alaska region, and ice-nucleating particles (INPs) in MPCs...

This is a poster presentation providing a visual representation of the research through text, charts, graphs. Mixed-phase clouds (MPCs), which contain both ice crystals and supercooled liquid droplets, are ubiquitous over the North Slope of Alaska region, and ice-nucleating particles (INPs) in MPCs impact the formation and modulation of MPCs, precipitation, and the solar energy budget. However, the role of MPCs and INPs on Arctic warming is not yet well revealed, which represents a substantial knowledge gap in climate science. As a first step towards filling the gap, in this work, we examine the role of high-latitude pressure core variability on the ground-level INP concentration as a surrogate parameter of ice cloud microphysics. To measure the INP abundance, we employed a Portable Ice Nucleation Experiment (PINE) chamber, which simulates virtual adiabatic expansion cooling in a 10 L aluminum vessel, at Barrow Atmospheric Baseline Observatory (71.32° N, 156.61° W).
