Research Highlights

 

Members of the Atmospheric Radiation Measurement (ARM) user facility‚Äôs science team are major contributors to radiation and cloud research. Scientists and investigators using ARM publish about 150 peer-reviewed journal articles per year, and ARM data are used in many studies published by other scientific organizations. These documented research efforts represent tangible evidence of ARM’s contribution to advances in almost all areas of atmospheric radiation and cloud research.

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 [...]

Measuring Ice Nucleating Activity in the Ambient Atmosphere

13 May 2022

Burrows, Susannah M.

Supported by: ASR

Research area: Aerosol Properties

Ice nucleating particles (INPs) are a rare subset of particles that can have an outsized impact on climate. To simulate the impacts of INPs, global climate models require simplified mathematical representations, or parameterizations, for the ice nucleation activities (IN-activities) of the most important INP sources. This work presents a method [...]
