Sentences with phrase «larger aerosol particles»

Larger aerosol particles greater than 100 nanometers, such as soot or black carbon, are known to help seed clouds.

Not exact matches

She decided to study the role that organic particles play in cloud droplet formation, because a large proportion of marine aerosols — which have a significant climate impact — are organics.

Where the atmosphere has few aerosol particles — over the ocean, for instance — water molecules have fewer particles to condense around, so cloud droplets are large.

Plants release gases that, after atmospheric oxidation, tend to stick to aerosol particles, growing them into the larger - sized particles that reflect sunlight and also serve as the basis for cloud droplets.

Two important aerosol species, sulfate and organic particles, have large natural biogenic sources that depend in a highly complex fashion on environmental and ecological parameters and therefore are prone to influence by global change.

«Particles of any kind, even much smaller than the wavelength of visible light, will, as a rule, make the sky brighter but at the expense of its purity of color,» Bohren says, noting that the effect is more pronounced when there is a high concentration of large aerosols.

* Yellow areas show where large and small aerosol particles are mixing.

Therefore, considering the large contribution of these particles to the aerosol mass concentration in the atmosphere and the importance of the INPs, we study the ability of these particles as INPs by immersion freezing mode.

Because small - scale climate features, such as clouds and atmospheric aerosol particles, have a large impact on global climate, it's important to improve the methods used to represent those climate features in the models.

Because much of Earth's land mass is covered by plants, there is a large source of these biogenic aerosol particles that need to be accounted for in climate change prediction.

A large portion of secondary organic aerosols - tiny particles in the air we breathe that contribute to cloud formation and precipitation - arise from a combination of man - made pollution and molecules given off by plant matter.

The CLOUD experiment consists of a large instrumented chamber in which the atmosphere can be precisely simulated, and the formation and growth of aerosol particles and the clouds they seed can be studied under precisely controled atmospheric conditions.

In this case, large amounts of sulphate aerosols (small particles) are injected into the stratosphere by large explosive eruptions (the most recent one being Mt. Pinatubo in 1991).

According to «Atmospheric particles and nuclei» by Götz et al. (1991), Junge (1963) proposed on the basis of aerosol measurements that «large» and «giant» particles (radius greater than 0.1 micro-meter) constitute the majority of CCN, independently of their chemical composition.

My question is: does the retroreflectivity of the larger droplets, i.e. back towards the light source, play into the sulfur aerosol issue or is it simply averaged out by the bulk effect of all the aerosol particles present in the apparently white haze?

The Muchachas project looked at organic aerosols, which constitute the largest proportion of chemical airborne particles.

While the standard suit of instruments deployed at the ground site (Eastern North Atlantic, ENA) can measure particle sizes between 2.5 nm and 1 um (using the Scanning Mobility Particle Sizer, SMPS and the Ultra-High Sensitivity Aerosol Spectrometer, UHSAS), there is still a need to measure larger paparticle sizes between 2.5 nm and 1 um (using the Scanning Mobility Particle Sizer, SMPS and the Ultra-High Sensitivity Aerosol Spectrometer, UHSAS), there is still a need to measure larger paParticle Sizer, SMPS and the Ultra-High Sensitivity Aerosol Spectrometer, UHSAS), there is still a need to measure larger particles.

Large volcanic eruptions eject sulfur dioxide, which rapidly forms tiny particles in the air known as «aerosols» that block sunlight.

This work eventually led to investigation of how planetary cooling might be caused by the aerosol particles arising from large - scale fires generated by a nuclear war.
