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.

A 19-month record of total, and single-layered low ( 6 kilometers) cloud fractions (CFs), and the single-layered marine boundary layer (MBL) cloud macrophysical and microphysical properties was generated from ground-based measurements at the ARM Azores site between June 2009 and December 2010. This is the most comprehensive data set of marine cloud fraction and MBL [...]

The growth of newly formed particles from sizes of less than three nanometers up to the sizes of cloud condensation nuclei (about one hundred nanometers) in many continental ecosystems require abundant, essentially non-volatile organic vapours. However, the sources and compositions of such vapors were previously unknown. This research found that ozonolysis of monoterpenes, a [...]

Over the North Slope of Alaska, researchers used cloud radar Doppler velocity spectra, lidar backscattering coefficients and depolarization ratios, and aircraft in situ measurements to investigate microphysical processes occurring in a case of multilayered, mixed-phase clouds.

Biomass burning (BB) is one of the largest sources of carbonaceous aerosols that are known to affect the radiative balance of the Earth (Bond et al. 2013). The net BB radiative forcing is small (0.0 ± 0.20Wm 2) (IPCC 2013), but very uncertain, due to the need to resolve the balance between the positive forcing [...]

There is an atmospheric particle not satisfied with only a single role in the climate. The ambitious culprit? Brown carbon aerosol steps outside the box and acts to both warm and cool the climate. A brown secondary organic aerosol (SOA) is thought to be created when gases that are emitted from both natural and man-made [...]
