Investigation of tropospheric arctic aerosol and mixed-phase clouds using airborne lidar technique
… was proved feasible for the low density mixed-phase cloud studies. An example of such approach during observation of the natural cloud seeding (feeder-seeder phenomenon) with ice crystals precipitating into the lower supercooled stratocumulus deck were discussed in terms of the lidar …

The phase separation inlet for droplets, ice residuals, and interstitial aerosols
A new inlet for studying the composition of mixed-phase clouds - the phaSe seParation Inlet for Droplets icE residuals and inteRstitial aerosols (SPIDER) - is described. SPIDER combines an omni-directional inlet, a Large-Pumped Counterflow Virtual Impactor (L-PCVI), a flow tube as evaporation …

An Investigation Of Cloud Processes Relevant To Climate Sensitivity
… characterization of the ice fall speed in cirrus clouds, ice nucleation in cirrus clouds and ground-based remote sensing of cloud properties in ice clouds and mixed phase clouds.Studies have shown that the ice fall speed determines one of the most important climate feedback processes. The mass …

Airborne lidar observations of tropospheric arctic clouds
… sensitive to climate changes. The influence of clouds on the radiation budget is substantial, but difficult to quantify and parameterize in models. In the framework of the PhD, elastic backscatter and depolarization lidar observations of Arctic clouds were performed during the international …

Assessing impact of the sulfate aerosol first indirect effect on tropical cyclone activity
… the goal of producing low-lying stratocumulus clouds to increase total cloud cover, but the single-column WTG scheme was not able to produce stratocumulus that did not also produce an overly strong negative feedback. Using the single-column model, one can demonstrate the indirect effect of …

The dependence of arctic mixed phase stratus ice cloud microphysics on aerosol concentration using observations acquired during ISDAC and M-PACE
… sorties on 9, 10 and 12 October 2004 during the Mixed Phase Arctic Cloud Experiment (M-PACE) were used to test three aerosol indirect effects hypothesized to act in mixed phase clouds: the riming indirect effect, the glaciation indirect effect, and the cold second indirect effect. By comparing …

Investigating the potential of meltwater as a local source of ice nucleating particles in the central Arctic summer
… socioeconomics 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 …

Validation, trend analysis & bias reduction through satellite fusion of the cloud-top height record from terra MODIS & MISR
Modeled clouds contribute the largest uncertainty in modeled responses to climate change. While significant uncertainties exist in predictions of the complicated pathways in which cloud amounts (CA), cloud-top heights (CTH) and cloud opacity respond to warmer temperatures, there is robust agreement …
