Sentences with phrase «from aerosol pollutants»

Not exact matches

It then combines with pollutants from combustion — mainly nitrogen oxides and sulfates from vehicles, power plants and industrial processes — to create tiny solid particles, or aerosols, no more than 2.5 micrometers across, about 1/30 the width of a human hair.

ARO scientists monitor a range of atmospheric phenomena, from the influence of gases and aerosols on Earth's climate to the impact of pollutants in the atmosphere.

The step from moisture to clouds involves cooling, seed particles (including pollutant aerosols) and global wind patterns that blow the moisture from its place of origin to its place of condensation.

Scientists are involved in the evaluation of global - scale climate models, regional studies of the coupled atmosphere / ocean / ice systems, regional severe weather detection and prediction, measuring the local and global impact of the aerosols and pollutants, detecting lightning from space and the general development of remotely - sensed data bases.

Similarly, simulations could not explain how aerosols carry pollutants thousands of miles away from the sources to pristine environments.

It then combines with pollutants from combustion — mainly nitrogen oxides and sulfates from vehicles, power plants and industrial processes — to create tiny solid particles, or aerosols, no more than 2.5 micrometers across, about 1/30 the width of a human hair.

The deployment enabled the study of how aerosol and cloud life cycles, including cloud - aerosol - precipitation interactions, are influenced by pollutant outflow from a tropical megacity.

Additional output from the ACCMIP runs will include concentration / mass of radiatively active species, aerosol optical properties, and radiative forcings (clear and all sky) as well as important parameters that do not directly influence climate such as hydroxyl, chemical reaction rates, deposition rates, emission rates, surface pollutants and diagnostics of tracer transport.

The total CO2 equivalent (CO2 - eq) concentration of all long - lived GHGs is currently estimated to be about 455 ppm CO2 - eq, although the effect of aerosols, other air pollutants and land - use change reduces the net effect to levels ranging from 311 to 435 ppm CO2 - eq (high agreement, much evidence).

The problem, these researchers argue, is that a 50 - year baseline includes the period from 1950 to 1970 when relatively lower greenhouse gas emissions and stronger mitigating factors (like emissions of sulfate aerosol, an industrial - era pollutant that actually lowers temperatures by reflecting sunlight) caused global temperatures to stall for two decades.

PNNL scientists found that secondary organic aerosols formed in the presence of the toxic pollutant known as polycyclic aromatic hydrocarbons (PAHs) trapped the PAH molecules inside, shielding them from degradation.

Today, the main answer to the question of what might be offsetting warming is «aerosols,» particularly sulfur and carbon compounds that are man - made pollutants (true pollutants) from burning fossil fuels.

The trans - boundary movement of people, water resources, aerosols, pollutants and CO fumes from wild and human - made fires are clearly charted on a both a continental and global scale.

Future climate change may cause significant air quality degradation by changing the dispersion rate of pollutants, the chemical environment for ozone and aerosol generation and the strength of emissions from the biosphere, fires and dust.
