Sentences with phrase «rays on aerosol»

CLOUD is designed to study the effects of cosmic rays on aerosols, cloud droplets and ice particles, under precisely controlled laboratory conditions.

Not exact matches

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.

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

They found that galactic cosmic rays exert only a small influence on the formation of sulphuric acid — dimethylamine clusters (the embryonic stage before aerosols may act as cloud condensation nuclei).

This paper re-states the grand Svensmark theory and attempts to address the work that has shown cosmic rays can not be a significant influence on climate because most aerosols run out of stuff to become big enough for cloud formation.

In summary the findings to date indicate that the effect of cosmic rays on cloud formation is small compared to the large variations in natural biogenic aerosol emissions.

Our model suggests that the effect of changes in cosmic ray intensity on CCN is small and unlikely to be comparable to the large variations in natural primary aerosol emissions.

The cosmic ray particles work let's say like a «glue» that puts together all the already formed condensation nuclei in the atmospheric air, creating therefore bigger condensation nuclei and finally the clouds, or the cosmic particles act as aerosols on their own, on which the water vapour condenses?

This was surprising and casts a pall on claims that cosmic ray ionization controls aerosol production.

There have been many studies aiming to test this hypothesis since AR4, 50 which fall in two categories: i) studies that seek to establish a causal relationship between cosmic rays and 51 aerosols / clouds by looking at correlations between the two quantities on timescales of days to decades, and 52 ii) studies that test through observations or modelling one of the physical mechanisms that have been put 53 forward.

7.4.5 Impact of Cosmic Rays on Aerosols and Clouds 43 44 High solar acti0vity leads to variations in the strength and three - dimensional structure of the heliosphere, 45 which reduces the flux of galactic cosmic rays (GCR) impinging upon the Earth's atmosphere by increasing 46 the deflection of low energy GCR.

He thought that this connection might occur via the effect of cosmic ray induced ionization on aerosol and cloud condensation nuclei and thus on the radiative properties of clouds.

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).
