Sentences with phrase «aerosol precursors»
The phrase "aerosol precursors" refers to substances or chemicals that can transform or react in the air to form aerosols. These aerosols are tiny particles suspended in the atmosphere, which can have various effects on the environment, climate, air quality, and human health. Aerosol precursors can come from natural sources, such as volcanoes or forest fires, as well as from human activities, like burning fossil fuels or using certain industrial processes. Full definition
Global climate models are essential tools for understanding climate change and for developing policy regarding future emissions of greenhouse gases, primary aerosol particles, and aerosol precursor gases.

Emissions of aerosol precursors from vegetation and from the marine biosphere are expected to respond to climate change.
In previous IPCC Assessments, a small number of future greenhouse gas and aerosol precursor emissions scenarios have been presented (e.g., Leggett et al., 1992).
Examples of such gaseous aerosol precursors are dimethyl sulfide (DMS) emitted by plankton or iodocompounds created by marine algae.
Emissions of sulfur aerosol precursors portray even more dynamic patterns in time and space than the CO2 emissions shown in Figure 1 - 6.
RF attributable to individual aerosol precursors including indirect cloud effects was not provided in AR5, and hence to incorporate this important component for SO2, BC and OC I use a combination of modeling and literature analysis (Shindell et al. 2012a; Shindell et al. 2009; United Nations Environment Programme and World Meteorological Organization 2011; hereafter UNEP 2011; see ESM).
We find that the increase in emissions of inorganic aerosol precursors is much larger than the corresponding aerosol increase, reflecting a non-linear atmospheric response.
Plants emit volatile compounds, which are tropospheric ozone and aerosol precursors.
The models used the Intergovernmental Panel on Climate Change's «A1B» mid-range projected emission scenarios for ozone and aerosol precursors, independently calculated the resulting composition change, and then performed transient simulations to 2050 examining the response to projected changes in the short - lived species and to changes in both long - lived and short - lived species together.
These sources have the lowest co-emissions of aerosols or aerosol precursors of all the major BC sources.
Emissions of gaseous and particulate species (i.e. aerosols, ozone and aerosol precursors) from anthropogenic activities and biomass burning have been estimated over the full period, using the 2000 dataset for harmonization of the past and current 1850 - 2000 emissions with the future emissions determined by the Integrated Assessment Models (IAMs) for the four IPCC Representative Concentration Pathways (RCPs).
Plants emit volatile compounds, which are tropospheric ozone and aerosol precursors.
