Research Highlights

 

Members of the ARM Climate Research Facility‚Äôs science team are major contributors to radiation and cloud research. Scientists and investigators using ARM facilities publish about 150 refereed journal articles per year, and ARM Facility data are used in many studies published by other scientific organizations. These documented research efforts represent tangible evidence of the ARM Facility’s contribution to advances in almost all areas of atmospheric radiation and cloud research.

Entrainment rate diurnal cycle in marine stratiform clouds

16 October 2017

Painemal, David

Supported by: ARM ASR

Research area: Cloud Processes

Cloud entrainment, the mixing of non-turbulent cloud-free air at the edges of the cloud layer, is a central mechanism governing cloud lifecycles within the cloud-topped marine boundary layer. Cloud-top entrainment across the inversion base regulates the boundary-layer turbulence and growth, as well as the cloud cover and microphysical evolution in [...]

ARM Cloud Radar Simulator: A New Tool for Bridging Field Data and Climate Models

10 October 2017

Xie, Shaocheng; Zhang, Yuying

Supported by: ARM ASR

Research area: Cloud Processes

Significant differences exist between how a climate model represents clouds and what instruments observe, both in terms of spatial scale and the properties of the hydrometeors that are either modeled or observed. To address these issues and minimize impacts of instrument limitations, this study developed an ARM radar simulator that [...]

Wildfire Particles Travel a Long Way from Home

10 October 2017

Fast, Jerome D

Supported by: ASR

Research area: Aerosol Properties

Impurities in surface snow reduce the snow’s surface reflectivity (albedo), which leads to heating of the snow. The magnitude of this effect depends on the concentration and season of deposition. Scientists at the U.S. Department of Energy (DOE) participated in a study that examined the processes contributing to the [...]
