Theoretical prediction of the homogeneous ice nucleation rate: disentangling thermodynamics and kinetics

Estimating the homogeneous ice nucleation rate from undercooled liquid water is crucial for understanding many important physical phenomena and technological applications, and challenging for both experiments and theory. From a theoretical point of view, d ...

Implementation of a comprehensive ice crystal formation parameterization for cirrus and mixed-phase clouds in the EMAC model (based on MESSy 2.53)

Athanasios Nenes

A comprehensive ice nucleation parameterization has been implemented in the global chemistry-climate model EMAC to improve the representation of ice crystal number concentrations (ICNCs). The parameterization of Barahona and Nenes (2009, hereafter BN09) al ...

A multi-year data set on aerosol-cloud-precipitation-meteorology interactions for marine stratocumulus clouds

Athanasios Nenes, Zheng Wang

Airborne measurements of meteorological, aerosol, and stratocumulus cloud properties have been harmonized from six field campaigns during July-August months between 2005 and 2016 off the California coast. A consistent set of core instruments was deployed o ...

Large wind farms can destroy stratocumulus clouds-evidence from large eddy simulations.

Varun Sharma, Michael Lehning, Marc Parlange, Marc Calaf Bracons

Stratocumulus is one of the most common cloud types found in the atmospheric boundary layer (ABL) and have been shown to have a significant impact on modulating the global radiation and energy balance. In spite of their ubiquitousness however, their shallo ...

Breaking size segregation waves in experimental bidisperse granular flows.

Tomás Alfredo Trewhela Palacios

In the leading edge of a bidisperse gravity-driven granular flow, two opposing mechanisms coexist: size-segregation and mixing. As a result of shear-induced particle segregation, large particles are displaced to upper layers of the flow where they move fas ...

A new method to retrieve the real part of the equivalent refractive index of atmospheric aerosols

Athanasios Nenes

In the context of the international experimental campaign Hygroscopic Aerosols to Cloud Droplets (HygrA-CD, 15 May to 22 June 2014), dry aerosol size distributions were measured at Demokritos station (DEM) using a Scanning Mobility Particle Sizer (SMPS) in ...

Regional Similarities and NOx-Related Increases in Biogenic Secondary Organic Aerosol in Summertime Southeastern United States

Athanasios Nenes, Satoshi Takahama, Giulia Ruggeri, Junqiu Liu

During the 2013 Southern Oxidant and Aerosol Study, Fourier transform infrared spectroscopy (FTIR) and aerosol mass spectrometer (AMS) measurements of submicron mass were collected at Look Rock (LRK), Tennessee, and Centreville (CTR), Alabama. Carbon monox ...

Intruders size-segregating under oscillating shear flows.

Christophe Ancey, Tomás Alfredo Trewhela Palacios

Granular geophysical flows are composed by particles of different sizes that segregate under the action of gravity and shear-induced dilatancy. Size segregation is the physical process by which small particle percolate through gaps left by the relative mov ...

From hygroscopic aerosols to cloud droplets: The HygrA-CD campaign in the Athens basin -- An overview

Athanasios Nenes

The international experimental campaign Hygroscopic Aerosols to Cloud Droplets (HygrA-CD), organized in the Greater Athens Area (GAA), Greece from 15 May to 22 June 2014, aimed to study the physico-chemical properties of aerosols and their impact on the fo ...
