The dependence of arctic mixed phase stratus ice cloud microphysics on aerosol concentration using observations acquired during ISDAC and M-PACE
… of Canada (NRC) Convair-580, equipped with cloud and aerosol probes during 5 sorties through single-layer arctic stratocumulus on 8 April, 18 April, and 26 April 2008 during the Indirect and Semi Direct Aerosol Campaign (ISDAC) and by the University of North Dakota Citation on 4 sorties on …

The impact of vertical variations of cloud mircrophysics and drizzle on the angular anisotropic behavior of weighted cloud droplet effective radius
The effective radius (Re) of the cloud droplet size distribution is an Essential Climate Variable identified by the Global Climate Observing System for its important role in energy and water cycle studies. It is retrieved simultaneously with optical depth (τ) from passive satellite imagers, like …

Investigating the potential of meltwater as a local source of ice nucleating particles in the central Arctic summer
… and Arctic livelihoods. Arctic mixed-phase clouds (AMPCs) are a pillar in the feedback systems by modulating the surface energy budget, depending on the partitioning of cloudwater between ice and liquid phases that is sensitive to the concentration of ice nucleating particles (INPs) in the …

Arctic Cloud, Radiation and their Interactions with Sea Ice
… coverage and thickness at impressive rates. The cloud-radiation feedback is believed to be one of the critical reasons for Arctic sea ice long-term trends and variability. Therefore, this study aims to investigate the role of cloud-radiation feedback in modulating Arctic sea ice changes from …

RELAMPAGO-CACTI drop size distribution observations and the implications for cloud and hydrologic studies
… light precipitation in vertically-pointing cloud radar data represent a unique characteristic of the Córdoba site relative to the other sites. As a result, the co-variability between DSD physical parameters indicates that the precipitation observed at Córdoba may confound existing drop size …

Observation and simulation of mid-latitude ice clouds
… are commonly used to obtain PSDs and other cloud microphysical properties. In particular, two-dimensional in situ images captured by cloud imaging probes are widely used to derive PSDs in term of their maximum particle dimension (Dmax). In the second chapter, different definitions of Dmax …

The use of gamma distributions to quantify the dependence of cloud particle size distributions in hurricanes on cloud and environmental conditions
… (TCs) are sensitive to the representation of cloud microphysical processes through their effect on modeled latent heat release. The cloud parameterizations used in such models make assumptions about the size distributions (SDs) of different ice species, such as cloud ice, graupel, and snow, …
