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

ARM data-oriented metrics and diagnostics facilitates use of field data in climate model evaluation

5 August 2020

Zhang, Chengzhu; Xie, Shaocheng

Supported by: ARM

Research area: General Circulation and Single Column Models/Parameterizations

Climate model developers often use a set of standard metrics and diagnostics as a way of routinely assessing general model performance or judging the performance of new physical parameterizations. ARM data can help to address a range of issues, including diagnosing summertime warm bias, the metrics of convective onset, precipitation [...]

Role of turbulent fluctuations in aerosol activation and cloud formation

27 July 2020

Cantrell, Will H.; Shaw, Raymond A

Supported by: ASR

Research area: Cloud-Aerosol-Precipitation Interactions

We examine the effects of fluctuations produced by turbulence. Our measurements, from the Pi chamber, show a clear transition from a regime in which the mean saturation ratio dominates to one in which the fluctuations determine cloud properties. We show cloud formation in mean-subsaturated conditions (i.e., relative humidity < 100%) in [...]
