Sentences with phrase «much aerosols in the atmosphere»

Not exact matches

Although the ions are not the most numerous constituents in the atmosphere the electro - magnetic interactions between ions and aerosols compensate for the scarcity and make fusion between ions and aerosols much more likely.

How much radiation is reflected by sulphur dioxide aerosols varies according to the size of the droplets, their height in the atmosphere, whether it is night or day, what season it is and several other factors.

Ultimately, scientists hope to learn how aerosols affect clouds, how much aerosols are produced by humans and nature and how they travel in the atmosphere.

«It is therefore reasonable to expect that precipitation extremes will continue to intensify,» although how much is still a mystery, largely thanks to an unclear understanding of the atmospheric impact of how tiny flecks of pollution in the atmosphere — known as aerosols to scientists and comprising materials ranging from soot to sulfur dioxide.

While a large amount of aerosols that exist in the Earth's atmosphere are naturally occurring — created by processes such as mechanical suspension by wind or sea spray — much is produced as a result of industrialization.

Scientists had attributed much of the dimming and brightening to changes in the amounts of tiny particles, or aerosols, in the atmosphere.

The second study meanwhile looked at how aerosol emissions impact the Earth's temperature through a phenomenon the researchers call «transient climate sensitivity,» or how much of the Earth's temperature will change when the amount of carbon dioxide in the atmosphere reaches twice its level during the pre-industrial times.

Meanwhile, production of greenhouse gases — which linger in the atmosphere much longer than sulfate aerosols — has continued, causing average global temperatures to rise.

But, much more important, models are not intended to predict well all the remaining physical variables of the weather - climate system that are all local in their essence: 3D - temperature (atmosphere and ocean), precipitation, 3D - wind (and ocean currents), 3D - radiance, 3D - cloudness, 3D - moisture content, 3D - aerosol concentration and transport, etc, etc, etc...

The final step, as yet far from completion, is to measure the actual temperature and concentration of each molecule at each point in the atmosphere — including methane, ozone, aerosols and much more.

A recent paper by Dr. Tami Bond and colleagues finds that carbon aerosols — particulates released into that atmosphere from a variety of human activities including diesel engines, open cook stoves, poorly filtered coal burning, and open burning, etc. — have played a much larger role in impacting the climate than has been previously recognized (and included in climate models).

It would involve gradually eliminating pollution from factories and tailpipes; replacing them with artificial aerosols in the upper atmosphere where they're much less likely to damage human health; and then hope nothing (else) goes seriously awry.

«Earth system models» include all that and much more: forests that can shrink or spread as conditions change; marine food webs that react as the oceans grow more acidic with carbon dioxide; and aerosol particles in the atmosphere that interact with greenhouse gases, enhancing or sapping their warming power.

Although previous research had seemed to indicate that aerosols could create a general cooling effect in the atmosphere — thus helping mitigate the effect of global warming — a new study has revealed that they may in fact warm it just as much as greenhouse gases.

Although satellites can used for example to obtain spatial distribution of temperature, clouds, water vapour, aerosols in the atmosphere it appears much more difficult to measure the physical characteristics of the oceans for example the distribution of the optical depth of the particles in the oceans.

Greenhouse gases have a much longer lifespan — or residence time — in the atmosphere than aerosols, which typically rain out after a few days or weeks.
