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.

Ice formed by contact freezing: Pressure matters, not just temperature

12 February 2018

Shaw, Raymond A

Supported by: ASR

Research area: Cloud Processes

The freezing of supercooled water can be triggered at unusually high temperatures, by agitating and deforming the water surface. It has long been observed that "contact" of supercooled water with a dry aerosol particle can cause efficient freezing, and the new observations suggest that this may be due to pressure [...]

Small Particles Play Large Role in Tropical Thunderstorms

Fan, Jiwen

Research area: Aerosol Properties

Aerosol-cloud interactions remain the largest uncertainty in climate projections. Ultrafine aerosol particles—less than 50 nanometers wide—can be abundant in the troposphere, but are conventionally considered too small to affect cloud formation. A unique set of observations from the Amazon allowed scientists, to study the role of aerosols in tropical storm [...]
