Impacts of potential CO2-reduction policies on air quality in the United States

Athanasios Nenes, Pengfei Liu

Impacts of emissions changes from four potential U.S. CO2 emission reduction policies on 2050 air quality are analyzed using the community multiscale air quality model (CMAQ). Future meteorology was downscaled from the Goddard Institute for Spac ...

Changes in dissolved iron deposition to the oceans driven by human activity: a 3-D global modelling study

Athanasios Nenes

The global atmospheric iron (Fe) cycle is parameterized in the global 3-D chemical transport model TM4-ECPL to simulate the proton- and the organic ligand-promoted mineral-Fe dissolution as well as the aqueous-phase photochemical reactions between the oxid ...

Differences between magnitudes and health impacts of BC emissions across the United States using 12 km scale seasonal source apportionment

Athanasios Nenes

Recent assessments have analyzed the health impacts of PM2.5 from emissions from different locations and sectors using simplified or reduced-form air quality models. Here we present an alternative approach using the adjoint of the Community Mult ...

The 2010 California Research at the Nexus of Air Quality and Climate Change (CalNex) field study

Athanasios Nenes

The California Research at the Nexus of Air Quality and Climate Change (CalNex) field study was conducted throughout California in May, June, and July of 2010. The study was organized to address issues simultaneously relevant to atmospheric pollution and c ...

Sampling and Reconstruction of Time-Varying Atmospheric Emissions

Martin Vetterli, Ivan Dokmanic, Juri Ranieri, Amina Chebira

We study the spatio-temporal sampling of physical fields representing the dispersion of a substance in the atmosphere. We consider the following setup: N sensors are deployed at ground level and measure the concentration of a particular substance, while M ...

Impact of fuel quality regulation and speed reductions on shipping emissions: Implications for climate and air quality

Athanasios Nenes

Atmospheric emissions of gas and particulate matter from a large ocean-going container vessel were sampled as it slowed and switched from high-sulfur to low-sulfur fuel as it transited into regulated coastal waters of California. Reduction in emission fact ...

2011

Growing population, consuming a large amount of energy such as combustion of fossil fuel, increasing pollutant emissions in the atmosphere are the threats to the sustainable development of our planet in general, and of the air quality in particular. Accord ...

EPFL2010

Road traffic emission factors (EFs) are one of the main sources of uncertainties in emission inventories; it is necessary to develop methods to reduce these uncertainties to manage air quality more efficiently. Recently an alternative method has been propo ...

2010

Understanding the surface O-3 response over a "receptor" region to emission changes over a foreign "source" region is key to evaluating the potential gains from an international approach to abate ozone (O-3) pollution. We apply an ensemble of 21 global and ...

Atmospheric composition change - global and regional air quality

Isabelle Bey, Sylvia Generoso

Air quality transcends all scales with in the atmosphere from the local to the global with handovers and feedbacks at each scale interaction. Air quality has manifold effects on health, ecosystems heritage and, climate. In this review the state of scientif ...
