Research Highlights

 

Members of the Atmospheric Radiation Measurement (ARM) user facility’s science team are major contributors to radiation and cloud research. Scientists and investigators using ARM publish about 150 peer-reviewed journal articles per year, and ARM data are used in many studies published by other scientific organizations. These documented research efforts represent tangible evidence of ARM’s contribution to advances in almost all areas of atmospheric radiation and cloud research.

Habit-dependent vapor growth modulates the macrophysical occurrence of arctic supercooled clouds

10 June 2021

Silber, Israel

Supported by: ARM ASR

Research area: Cloud Distributions/Characterizations

Analysis of long-term data collected at Utqiaġvik, Alaska to explore the impacts of cloud processes on the probability of finding supercooled water given cloud temperature in the topmost unseeded liquid-bearing layers indicates that habit-dependent vapor growth of ice crystals modulates the macrophysical occurrence of supercooled water in polar clouds.

Aerosol direct radiative effects at the ARM SGP and TWP sites: Clear skies

28 May 2021

Fu, Qiang

Supported by: ARM ASR

Research area: Radiation Processes

The objective of this project is to examine and quantify aerosol direct radiative effects (DREs) and associated uncertainties at the U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) user facility's Southern Great Plains (SGP) and Tropical Western Pacific (TWP) sites under all sky conditions by taking advantage of the [...]

Investigation of turbulent entrainment mixing with high-resolution digital holography

28 May 2021

Liu, Yangang

Supported by: ARM ASR

Research area: Cloud-Aerosol-Precipitation Interactions

Turbulent entrainment-mixing processes have been proposed to explain outstanding cloud physics problems such as spectral broadening and rain initiation. However, investigations of these processes have been limited by the lack of high-resolution measurements and the apparent dependence of entrainment-mixing mechanisms on sampling scale. This study takes advantage of the cm-resolution [...]
