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.

Estimation of pressure perturbations needed to explain contact nucleation

21 January 2020

Yang, Fan; Vogelmann, Andrew M.

Supported by: ASR

Research area: Cloud Processes

The pressure perturbation hypothesis, which arose from recent lab experiments, has been proposed to explain the long-standing mystery of contact nucleation. However, validating the hypothesis is extremely difficult as it would require measuring pressure perturbations caused by the impact of ice nucleating particles on supercooled droplets. Instead, we improve understanding [...]

"Fungal shrapnel" found in the air during HI-SCALE

21 January 2020

Smith, James; Lawler, Michael Joseph

Supported by: ARM ASR

Research area: Aerosol Processes

During summer 2016 at the Holistic Interactions of Shallow Clouds, Aerosols, and Land-Ecosystems (HI-SCALE) Field Campaign, we found fragments of biological cells in the atmosphere that were many times smaller and many times more numerous that we knew existed. These fragments are most likely bits of fungal spores that have burst [...]

Episodes of warm‐air advection causing cloud‐surface decoupling during MARCUS

21 January 2020

Zheng, Youtong Youtong Zheng

Supported by: ARM ASR

Research area: Cloud Processes

Ship observations show that marine clouds can be highly detached from the underlying sea surface fluxes if the clouds move from warm to cold water.
