This study explores the complex interactions between ice clouds and precipitation, focusing on the Ice Water Content (IWC) across various atmospheric conditions. We assess total extinction and snow mass at Arctic sites to minimize blowing snow effects. The research employs advanced instruments, including nadir and forward-looking lidar/radar and in-situ probes, to gather comprehensive datasets. Through a multi-aircraft campaign modeled after STORMVEX, we aim to improve the climatology of IWC, particle size distribution, and extinction for better understanding and forecasting of atmospheric phenomena.

Ice Clouds and Precip • Needs • IWC across the full range (IKP; HIWC campaign) • Total extinction • Snow mass (and size) at the surface at Arctic sites (minimize effects of blowing snow) • Ice crystal shape • Vertical correlations among datasets • IR constraint • Limited datasets with full complement of new probes • Potential Actions • Climatology of IWC, PSD, Extinction with full complement of instruments • Multi-Aircraft campaign (nadir lidar/radar + in situ probes + forward looking lidar/radar) • STORMVEX type campaign (in situ on mtn top with remote sensors pointing toward location)
