Sentences with phrase «aerosol layer»
An aerosol layer refers to a region in the Earth's atmosphere where tiny particles, like dust, smoke, or pollutants, are suspended and spread out. These particles can have various effects on our climate, air quality, and even affect the formation of clouds. Full definition
«This is one study where I am not eager to have our predictions proven right by a global stratospheric aerosol layer in the real world.»

When sulfur dioxide emitted by a volcano rises up to the stratospheric aerosol layer of the atmosphere, it undergoes chemical reactions, forming particles that reflect sunlight back into space instead of letting it get to the surface of the planet.
He called it the Asian tropopause aerosol layer (ATAL) because it lies within the tropopause, a transitional zone spanning the upper troposphere and lower stratosphere.
It is found that with a number concentration of aerosol particles of ∼ 102 — 103 cm − 3 (which corresponds to the aerosol density in the deposited layer of about 1 — 10 mg / m2 with the layer thickness along the ray path of about 100 m) the solar radiation attenuation with artificial aerosol layers accounts for 1 to 10 %.
Vernier, J. - P., L.W. Thomason, et al. 2011: Major influence of tropical volcanic eruptions on the stratospheric aerosol layer during the last decade.
Recent measurements demonstrate that the «background» stratospheric aerosol layer is persistently variable rather than constant, even in the absence of major volcanic eruptions.
An aerosol layer forms; the original scientific term was dust veil.
A veil or aerosol layer that stems from an eruption in the tropics spreads first around Earth's equatorial belt, the so - called tropical pipe, and then flows north and south toward the poles.
The Persistently Variable «Background» Stratospheric Aerosol Layer and Global Climate Change
Scientists can calculate the distance between the instrument and the object, based on the time it takes the energy to return to the receiver, thereby determining the altitudes of cloud and aerosol layers.
With beams at three wavelengths (1064, 532, and 355 nanometers), CATS will be used to derive a variety of properties of cloud and aerosol layers.
In fact, the aerosol layer in the stratosphere, which is also composed of sulphur particles, seems to have become thicker in recent years.
«The Persistently Variable «Background» Stratospheric Aerosol Layer and Global Climate Change.»
The authors of the new study used computer simulations to see which changes in the stratospheric aerosol layer could be attributed to coal burning in Asia and worldwide volcanic emissions from 2000 to 2010.
Recent measurements demonstrate that the «background» stratospheric aerosol layer is persistently variable rather than constant, even in the absence of major volcanic eruptions.
Cloud - resolving models of cumulus and stratocumulus case studies also diagnose semi-direct effects indicating a similar relationship between the height of the aerosol layer relative to the cloud and the sign of the semi-direct effect (Ackerman et al., 2000; Ramanathan et al., 2001; Johnson et al., 2004; Johnson, 2005).
As aerosols cool the Earth's surface and warm the aerosol layer, the lapse rate will decrease globally and suppress the water vapour feedback (e.g., Feichter et al., 2004).
