Global atmospheric particle formation from CERN CLOUD measurements

Fundamental questions remain about the origin of newly formed atmospheric aerosol particles because data from laboratory measurements have been insufficient to build global models. In contrast, gas-phase chemistry models have been based on laboratory kinet ...

Improving our fundamental understanding of the role of aerosol-cloud interactions in the climate system

Athanasios Nenes

The effect of an increase in atmospheric aerosol concentrations on the distribution and radiative properties of Earth's clouds is the most uncertain component of the overall global radiative forcing from preindustrial time. General circulation models (GCMs ...

Meteorological and aerosol effects on marine cloud microphysical properties

Athanasios Nenes, Robin Lewis Modini, Zheng Wang

Meteorology and microphysics affect cloud formation, cloud droplet distributions, and shortwave reflectance. The Eastern Pacific Emitted Aerosol Cloud Experiment and the Stratocumulus Observations of Los-Angeles Emissions Derived Aerosol-Droplets studies p ...

Enhanced formation of isoprene-derived organic aerosol in sulfur-rich power plant plumes during Southeast Nexus

Athanasios Nenes, Hairun Guo, André Welti

We investigate the effects of anthropogenic sulfate on secondary organic aerosol (SOA) formation from biogenic isoprene through airborne measurements in the southeastern United States as part of the Southeast Nexus (SENEX) field campaign. In a flight over ...

CCN properties of organic aerosol collected below and within marine stratocumulus clouds near Monterey, California

Athanasios Nenes

The composition of aerosol from cloud droplets differs from that below cloud. Its implications for the Cloud Condensation Nuclei (CCN) activity are the focus of this study. Water-soluble organic matter from below cloud, and cloud droplet residuals off the ...

Primary marine aerosol-cloud interactions off the coast of California

Athanasios Nenes, Robin Lewis Modini, Zheng Wang

Primary marine aerosol (PMA)-cloud interactions off the coast of California were investigated using observations of marine aerosol, cloud condensation nuclei (CCN), and stratocumulus clouds during the Eastern Pacific Emitted Aerosol Cloud Experiment (E-PEA ...

Atmospheric new particle formation as a source of CCN in the eastern Mediterranean marine boundary layer

Athanasios Nenes

While cloud condensation nuclei (CCN) production associated with atmospheric new particle formation (NPF) is thought to be frequent throughout the continental boundary layers, few studies on this phenomenon in marine air exist. Here, based on simultaneous ...

A synthesis of cloud condensation nuclei counter (CCNC) measurements within the EUCAARI network

Athanasios Nenes

Cloud condensation nuclei counter (CCNC) measurements performed at 14 locations around the world within the European Integrated project on Aerosol Cloud Climate and Air Quality interactions (EUCAARI) framework have been analysed and discussed with respect ...

Incorporating an advanced aerosol activation parameterization into WRF-CAM5: Model evaluation and parameterization intercomparison

Yi Zhang, Athanasios Nenes, Xiuwei Zhang

Aerosol activation into cloud droplets is an important process that governs aerosol indirect effects. The advanced treatment of aerosol activation by Fountoukis and Nenes (2005) and its recent updates, collectively called the FN series, have been incorpora ...
