Sentences with phrase «on aerosol nucleation»

To test their effect on aerosol nucleation, Kirkby's team fired beams similar to cosmic rays through the chamber and found it increased nucleation between 2 and 10 times.

Subsequently we will investigate the effects of these vapours on the nucleation and growth of aerosols.

Prior to the publication of the aerosol nucleation results from the CLOUD experiment at CERN in Nature several weeks ago Kirkby et al, 2011, I was asked by Nature Geoscience to write a «News and Views» on the CLOUD results for a general science audience.

Regarding the CERN / CLOUD results suggesting an aerosol nucleation link with cosmic - rays, I was wondering why the focus is always on clouds?

Perhaps surprisingly, the key innovation in this experimental set up is not the presence of the controllable ionisation source (from the Proton Synchrotron accelerator), but rather the state - of - the - art instrumentation of the chamber that has allowed them to see in unprecedented detail what is going on in the aerosol nucleation process (this is according to a couple of aerosol people I've spoken about this with).

It has been hypothesized that galactic cosmic rays (GCR) create atmospheric ions which facilitates aerosol nucleation and new particle formation with a further impact on the cloud formation (Kazil et al., 2012; Pierce and Adams, 2009).

In the article «Global atmospheric particle formation from CERN CLOUD measurements,» sciencemag.org, 49 authors concluded «Atmospheric aerosol nucleation has been studied for over 20 years, but the difficulty of performing laboratory nucleation - rate measurements close to atmospheric conditions means that global model simulations have not been directly based on experimental data.....
