Sentences with phrase «biogenic voc»

Over the studied decade, the computed natural variations (8 %) in the chemical SOA production from biogenic VOC oxidation equal the chemical SOA production from anthropogenic VOC oxidation.

The SOA computed variability results from a 7 % increase in biogenic VOC emissions from 1986 to 1990 combined with 8.5 % and 6 % increases in the wet and dry deposition of SOA and leads to about 11.5 % increase in the SOA burden of biogenic origin.

It also reveals the existence of significant positive and negative feedback mechanisms in the atmosphere responsible for the non linear relationship between emissions of biogenic VOC and SOA burden.

Emission estimates of biogenic VOC (BVOC) and anthropogenic gases and particles from the literature for the year 2100 have been adopted.

The response of biogenic secondary organic carbon aerosol production to a temperature change, however, could be considerably lower than the response of biogenic VOC emissions since aerosol yields can decrease with increasing temperature.

Global biogenic VOC emissions respond to climate change (e.g., Turner et al., 1991; Adams et al., 2001; Penner et al., 2001; Sanderson et al., 2003b).

Biogenic VOC emissions may be highly sensitive to climate change.

In collaboration with scientists at the National Oceanic and Atmospheric Administration's (NOAA) Geophysical Fluid Dynamics Laboratory and several universities, this position will help develop a new set of chemical mechanism for biogenic VOC oxidation and SOA formation.

«When biogenic VOCs are oxidized, they give rise to aerosol particles that cool the climate by reflecting part of the Sun's radiation back into space,» Artaxo said.

Not exact matches

Such model included meteorological factors like levels of aerosols, anthropogenic and biogenic volatile organic compounds (VOCs), ozone, carbon dioxide, methane, and other items that influence global temperature — the surface albedo among them.

The successful candidate will study secondary organic aerosol (SOA) formation from the oxidation of biogenic volatile organic compounds (VOCs).

The considered emissions of biogenic non-methane volatile organic compounds (VOC) are driven by temperature, light and vegetation.
