Members of ARM's science team are major contributors to radiation and cloud research. ARM investigators publish about 150 refereed 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. Below is a selection of summaries highlighting recently-published ARM research. The entire collection of ARM Research Highlights can be accessed using the sorting buttons at right.

During our study, we observed that aerosol concentration and composition at a rural site in the Northeastern U.S. were influenced strongly by upwind urban emissions. A possible reason is that anthropogenic pollutants advected from urban areas interacted with biogenic emissions in the rural region and led to a substantial enhancement of secondary organic aerosol production.

The first few hours following the formation of a new atmospheric aerosol particle are a competition between the growth of the particle due to the condensation of low volatility “sticky” gases and the loss of the particle by collisions with other aerosol particles. New observations from the Cosmics Leaving Outdoor Droplets (CLOUD) chamber at CERN [...]

A multi-sensor effort that blends observations from UND Citation aircraft spirals and ground-based ARM scanning precipitation and cloud radars to investigate the signatures associated with riming and aggregation processes.

Knowledge of ice crystal particle size distributions (PSDs) is critical for development of microphysical parameterization schemes for numerical models and remote-sensing retrieval algorithms. Two-dimensional in situ images captured by cloud-imaging probes on aircraft are widely used to derive PSDs in term of maximum particle dimension (Dmax). However, inconsistencies in the definition of Dmax used in [...]

Isoprene is a biogenic volatile organic compound that, when oxidized by sunlight, heavily influences atmospheric chemistry over forested areas. Using field measurements from the ground and the air, this paper tracked the fate of isoprene over the central Amazon for eight weeks during the wet season. The main research site, 70 kilometers downwind of the [...]
