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

Scientists from around the world conduct research using data from ARM’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 to deploying an ARM Mobile Facility to remote locations around the world. As a scientific user facility, any scientist can submit a proposal to do field campaigns at ARM’s atmospheric observatories.


Data from ARM’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

Air pollution unable to intensify storms via warm-phase invigoration

13 January 2023

Romps, David

Supported by: ARM ASR

Research area: Cloud-Aerosol-Precipitation Interactions

Of the mechanisms proposed for how aerosols might invigorate storms, the observational evidence on supersaturation makes the warm-phase mechanism unlikely. An actively debated hypothesis is that air pollution from human activities regularly makes storms around the world more intense. In the "warm-phase invigoration mechanism," extra particles of air pollution (aerosols) release [...]

Sizing ice hydrometeors using the dual-wavelength radar ratio

5 January 2023

Matrosov, Sergey

Supported by: ASR

Research area: Cloud Processes

The ice cloud feedback in weather and climate models is strongly affected by the size of cloud particles. The snowflake size information is also important for improving the accuracy of weather radar-based snowfall quantitative precipitation estimation (QPE) techniques. Measurements of dual-wavelength radar ratio (DWR, i.e., the ratio of radar reflectivities [...]
