Research Highlights

 

Members of the Atmospheric Radiation Measurement (ARM) user facility‚Äôs 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.

Analytical expression of marine stratocumulus virga depth evaluated with observations

15 June 2018

Yang, Fan; Vogelmann, Andrew M.

Supported by: ARM ASR

Research area: Cloud Processes

Virga is drizzle below cloud base that evaporates before reaching the Earth’s surface. Virga results from the interaction of many different cloud processes with the environment. Researchers at Brookhaven National Laboratory and Michigan Technological University obtained virga statistics from observations and derived a new, simple analytical expression for drizzle virga [...]

WRF hindcasts of cold front passages over the ARM Eastern North Atlantic site

13 June 2018

Naud, Catherine M.; Booth, James

Supported by: ARM ASR

Research area: Cloud Processes

Low-level clouds behind extratropical cyclone cold fronts are a significant source of biases in General Circulation Models (GCMs), and the ARM East North Atlantic (ARM-ENA) site offers a great opportunity to address this problem. In order to isolate and compare the cloud-scale physics involved in low-level clouds with observations from [...]

Global, remotely sensed ice production in mid-level stratiform mixed-phase clouds

12 June 2018

Zhang, Damao; Vogelmann, Andrew M.

Supported by: ASR

Research area: Cloud Processes

Ice particle production in supercooled liquid clouds has a dramatic impact on the clouds' radiative properties, but it is not well understood and parameterized in models. Mid-level stratiform mixed-phase clouds have a simple dynamic environment and straightforward ice growth trajectory that enables using radar reflectivity measurements to quantitatively infer variations [...]
