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.

Inferring ice hydrometeor shapes from polarimetric radar measurements

8 January 2018

Matrosov, Sergey; de Boer, Gijs

Supported by: ARM ASR

Research area: Cloud Processes

Ice cloud and precipitation particle types and shapes (habits) influence important microphysical (e.g., crystal growth, evaporation, and sedimentation rates) and radiative (e.g., longwave and shortwave extinction and scattering) processes in the atmosphere. Quantifying particle shapes is critical for refining ice microphysical parameterizations in numerical models and improving quantitative precipitation estimation [...]

Local air pollution on Alaska's North Slope changes cloud properties

21 December 2017

Maahn, Maximilian; de Boer, Gijs

Supported by: ARM ASR

Research area: Cloud-Aerosol-Precipitation Interactions

Local air pollution on Alaska's North Slope appears to affect liquid clouds that form downwind, leading to smaller droplets less likely to fall as drizzle or rain, according to new research. Clouds in the region can either cool or warm the surface, depending on their specific properties and season. In [...]

The importance of updraft width

19 December 2017

Trapp, Robert Jeff; Nesbitt, Steve

Supported by: ASR

Research area: Vertical Velocity

Vertical wind shear exerts a strong control on the width of thunderstorm updrafts and, in turn, on the width of thunderstorm downdrafts and the depth of associated cold pools.
