ARM’s continuous measurements and field campaigns are helping advance climate science.

Scientists from around the world conduct research using data from the ARM Climate Research Facility’s continuous measurements and field campaigns. ARM’s contributions to atmospheric science can be seen in science publications and research highlights.

Field Campaigns

Field campaigns provide a means for scientists to augment or modify the configuration of the ARM Facility to address specific science issues. Campaigns range in complexity from deploying a single instrument deploying an ARM Mobile Facility. As a scientific user facility, any scientist can submit a proposal to do field campaigns at ARM’s atmospheric observatories.


Data from the ARM Facility’s continuous measurements and field campaigns at sites around the world are a vital asset to atmospheric researchers. Research results are published in scientific journal articles, conference publications, and presentations.

Research Highlights

Publications in scientific journals represent tangible evidence of ARM’s contribution to advances in almost all areas of atmospheric radiation and cloud research. ARM’s Research Highlights summarize recently published research results.

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

Ovchinnikov, Mikhail

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.
