Sentences with phrase «other atmospheric aerosols»

To investigate the layers and composition of clouds and tiny airborne particles like dust, smoke and other atmospheric aerosols,, scientists at NASA's Goddard Space Flight Center in Greenbelt, Maryland have developed an instrument called the Cloud - Aerosol Transport System, or CATS.

Not exact matches

Other aerosols can bring about temporary atmospheric cooling, mainly by seeding clouds that linger in the atmosphere longer than they normally would, or by scattering light.

The relative atmospheric concentrations of greenhouse gases as well as aerosol and particulate content coupled with other climate information gives insight into both the importance of these as drivers of temperature as well as how these drivers might couple in either a positive or negative feedback sense (Beckman and Mahoney, 1998).

This method tries to maximize using pure observations to find the temperature change and the forcing (you might need a model to constrain some of the forcings, but there's a lot of uncertainty about how the surface and atmospheric albedo changed during glacial times... a lot of studies only look at dust and not other aerosols, there is a lot of uncertainty about vegetation change, etc).

Greenhouse gases are well mixed and have an effect globally, other forcings may be more regional (aerosols, land use) but they can still have far field affects due to the nature of the atmospheric circulation.

On the other hand I am co-plotting, down to sub-annual timescales up to 3 or even perhaps 4 well defined physical parameters relating to both the sea surface (e.g. SST, chlorophyll a, surface leaving radiance), the immediate subsurface (e.g. diffuse attenuation of 490 nm light to approx 50 m depth) and atmospheric aerosol size e.g. AOT at 865 and 890 nm — all measured with modern, state of the art surface telemetry and remote sensing methods and simply looking for mechanistic links between these parameters on sub-annual timescales.

An international team of researchers report in Nature Communications that they made a computer model of the planet's atmospheric conditions: they included natural and human - triggered aerosols, volatile organic compounds, greenhouse gases and other factors that influence temperature, one of which is albedo: the scientist's word for the capacity of terrain to absorb or reflect solar radiation.

Such mixtures of absorbing and scattering aerosols (including other particulate matter such as nitrate, potassium and so on) are referred to as ABCs, for atmospheric brown clouds11» https://www.nature.com/articles/ngeo918

In turn, these optical depths may be used to derive information about the column abundances of ozone and water vapor, as well as aerosol and other atmospheric constituents.

Like other tiny atmospheric particles called aerosols, black carbon (BC) has a short lifetime in the atmosphere of about a week because it is removed by rain or snow.

Putting those two, theoretical, processes together with some shaky assumptions about aerosols, clouds and other atmospheric phenomena, and arriving at an assumption that the theoretical minor warming of CO2 is tripled is what concerns a true skeptic.

temperature, other climatic variables, and concentrations of aerosols and trace gases; and (2) making raw and processed atmospheric measurements accessible in a form that enables a number of different groups to replicate and experiment with the processing of the more widely disseminated data sets such as the MSU tropospheric temperature record.

On the other hand, theory shows that sulfuric acid / water aerosols are not stable by themselves requiring amines to stabilize and measurements with an atmospheric pressure inlet time of flight mass spectrometer showed that the intermediate aerosols did incorporate amines.

We need to know more about things like continental distribution, ocean currents, ice sheet coverage, solar output, atmospheric composition for other relevant species — O3, CH4, and H2O just to name a few — not to mention dust, and aerosols.

Indeed, all SLAP assertions can be explained by other factors (i.e., well known behavior of aircraft contrails and atmospheric aerosols).

In this and other articles dealing with global warming, there is a disturbing tendency to view atmospheric aerosols, as beneficial because of their cooling effect.

Theoretical and Applied Climatology covers climate modeling, climatic changes and climate forecasting, micro - to mesoclimate, applied meteorology as in agro - and forestmeteorology, biometeorology, building meteorology and atmospheric radiation problems as they relate to the biosphere; effects of anthropogenic and natural aerosols or gaseous trace constituents; hardware and software elements of meteorological measurements, including techniques of remote sensing, among other topics of current interest.

The relative atmospheric concentrations of greenhouse gases as well as aerosol and particulate content coupled with other climate information gives insight into both the importance of these as drivers of temperature as well as how these drivers might couple in either a positive or negative feedback sense.

The relative atmospheric concentrations of greenhouse gases as well as aerosol and particulate content coupled with other climate information gives insight into both the importance of these as drivers of temperature as well as how these drivers might couple in either a positive or negative feedback sense (Beckman and Mahoney, 1998).

Read more: Stanford University Aerosols Also Implicated in Glacier Melting, Changing Weather Patterns Other research examining the effects of soot on melting glaciers and changing weather pattens in South Asia has reached similar conclusions: Beyond increasing atmospheric warming, because the soot coats the surface of the snow and ice it changes the albedo of the surface, allowing it to absorb more sunlight and thereby accelerating melting.

I do need to check whether all of the 78 W / m ^ 2 is said to be absorbed in the absorption wavelengths of GHGs or whether some of this is component is absorbed in the absorption wavelenghts of other gases and / or by atmospheric aerosols.

Because of the combination of high absorption, a regional distribution roughly aligned with solar irradiance, and the capacity to form widespread atmospheric brown clouds in a mixture with other aerosols, emissions of black carbon are the second strongest contribution to current global warming, after carbon dioxide emissions.

Further, within my field, atmospheric chemistry, we are very much focused on the other forcings; aerosol and tropospheric ozone, for instance.

The identification of other, sometimes more powerful, greenhouse gases such as methane, the contributions to atmospheric carbon dioxide from other human activities such as deforestation and cement manufacture, better understanding of the temperature - changing properties of atmospheric pollution such as sulphur emissions, aerosols and their importance in the post-1940s northern hemisphere cooling: the knowledge - base was increasing year by year.

Called ModelE, it provides the ability to simulate many different configurations of Earth System Models — including interactive atmospheric chemistry, aerosols, carbon cycle and other tracers, as well as the standard atmosphere, ocean, sea ice and land surface components.

The term Earth System Model is a little ambiguous with some people reserving that for models that include a carbon cycle, and others (including me) using it more generally to denote models with more interactive components than used in more standard (AR4 - style) GCMs (i.e. atmospheric chemistry, aerosols, ice sheets, dynamic vegetation etc.).
