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.

Recent Highlights

Why do general circulation models overestimate the aerosol cloud lifetime effect?

21 March 2017

Penner, Joyce E.

Supported by: ARM ASR

Research area: Cloud-Aerosol-Precipitation Interactions

Traditionally, aerosols have been thought to lengthen cloud lifetime by increasing droplet number and reducing droplet size, thereby delaying and reducing the formation of rain in clouds. These longer-lived clouds would then increase cloud cover and reflect more sunlight. Yet observational evidence for these lifetime effects is limited and contradictory. [...]

Low-aerosol conditions over the Azores occur during marine cold air outbreaks.

Wood, Robert

Supported by: ARM ASR

Research area: Cloud-Aerosol-Precipitation Interactions

Current estimates suggest that between one-quarter and two-thirds of all cloud condensation nuclei in the atmosphere may be a direct result of human activities. Climate models suggest that brighter clouds are masking a significant fraction of the global warming that the Earth would be experiencing if aerosol particle concentrations had [...]
