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

High temporal resolution estimates of Central Arctic snowfall during the MOSAiC expedition

19 May 2022

Matrosov, Sergey

Supported by: ARM ASR

Research area: Cloud Processes

Measurements of snowfall, which is a crucial element of the Earth climate system, has been extremely scarce in the Central Arctic. A number of snowfall sensors including gauges, optical sensors and radars were deployed as part of the year-long Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition [...]

Machine Learning Techniques Speed Up Aircraft Aerosol Mass Spectrometer Analyses

18 May 2022

Shrivastava, Manishkumar

Supported by: ARM ASR

Research area: Aerosol Properties

Human and natural emissions contribute to the formation of fine particles in the atmosphere, including organic aerosols (OA). Aerosol mass spectrometers (AMS) are widely used to measure the composition of organic aerosols. Commonly, researchers use the positive matrix factorization (PMF) technique to derive the mass fractional contributions of different sources [...]
