Research Highlights


Members of the ARM Climate Research Facility’s 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.

Looking at Clouds From Both Sides Now

25 January 2017

Ghan, Steven J.; Zhang, Zhibo

Funded by:

Research area: Cloud Distributions/Characterizations

The impact of clouds on the reflection of sunlight to space depends on two key properties: cloud optical depth and droplet effective radius. Satellites provide nearly global coverage of these cloud properties, but the accuracy of the retrievals has not been evaluated. This study used ground-based retrievals to evaluate the [...]

Less is More: Low Aerosol Concentrations Produce High Variability in Cloud Droplet Sizes

7 January 2017

Shaw, Raymond A

Funded by: ASR

Research area: Cloud Processes

Clouds form when water vapor in the atmosphere condenses around airborne particles, or aerosols, but the exact details of the process remain relatively unknown. Researchers used large-eddy simulations (LES) to model cloud droplets that formed in Michigan Technological University’s cloud chamber by injecting various amounts of aerosols. They found that [...]

To Evaporate or Not To Evaporate: The Question of Secondary Organic Particulate Matter Lability

7 January 2017

Martin, Scot T.

Funded by: ASR

Research area: Aerosol Properties

New research highlights a nonlabile-to-labile transition for material representative of anthropogenic secondary organic particulate matter at a threshold humidity range. This behavior differs markedly from materials representing biogenic aerosol sources, which lack such a transition.
