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.

Inferring ice hydrometeor shapes from polarimetric radar measurements

8 January 2018

Matrosov, Sergey; de Boer, Gijs

Supported by: ARM ASR

Research area: Cloud Processes

Ice cloud and precipitation particle types and shapes (habits) influence important microphysical (e.g., crystal growth, evaporation, and sedimentation rates) and radiative (e.g., longwave and shortwave extinction and scattering) processes in the atmosphere. Quantifying particle shapes is critical for refining ice microphysical parameterizations in numerical models and improving quantitative precipitation estimation [...]

Local air pollution on Alaska's North Slope changes cloud properties

21 December 2017

Maahn, Maximilian; de Boer, Gijs

Supported by: ARM ASR

Research area: Cloud-Aerosol-Precipitation Interactions

Local air pollution on Alaska's North Slope appears to affect liquid clouds that form downwind, leading to smaller droplets less likely to fall as drizzle or rain, according to new research. Clouds in the region can either cool or warm the surface, depending on their specific properties and season. In [...]
