Backward trajectories of individual Asian dust storm (ADS) events were calculated using the hybrid single particle Lagrangian integrated trajectory (HYSPLIT) at four representative stations in Korea. A total of 743 ADS events and associated 2229 (endings of altitudes at 1000 m, 1500 m, and 2000 m per ADS event) backward trajectories from four stations were traced from January 2003 to August 2015. Regardless of the locations of the observed stations and the threshold time divide, recent increase of ADS occurrence rate was statistically significant in 99.9 % confidence limit.

The impact of black carbon emissions on human health and climate are of global interest. Despite this, black carbon emission factors for marine engines and fuels are uncertain because of the challenges of measuring black carbon emissions.

Although many time-series studies have established associations of daily pollution variations with daily deaths, there are fewer at low concentrations, or focused on locally generated pollution, which is becoming more important as regulations reduce regional transport. Causal modeling approaches are also lacking. Researchers used causal modeling to estimate the impact of local air pollution on mortality at low concentrations.

KOLKATA: The skyline on this part of the country turns grey by afternoon. By dusk, a thick layer of smog envelops the horizon.

Diesel engines power the dominant share of goods movement, construction equipment, and public transport vehicles in the global economy. This report presents a global strategy to reduce fine particulate (PM2.5) and black carbon emissions from the global fleet of on-road diesel vehicles. The strategy identifies 36 countries for immediate action.

Controversy exists about the differences in air pollution exposure and inhalation dose between mode of transport. We aimed to review air pollution exposure and inhaled dose according to mode of transport and pollutant and their effect in terms of years of life expectancy (YLE).

The results of the November 8 polls could have profound implications for the global architecture on climate change, given the publicly stated position of Republican candidate Donald Trump on this i

The European Investment Bank (EIB) has completed an analysis of its standards, criteria and procedures in relation to short-lived climate pollutants. The EIB also looked into the projects and sectors that it finances, the impacts they have on SLCP emissions and where the bank can scale up financing of projects that mitigate these emissions.

This protocol was developed and subsequently tested in 2012–2015 by Nordic test and research institutes, with Danish Technological Institute as project manager.

Within the framework of air quality studies at the megacity scale, highly time-resolved volatile organic compound (C2–C8) measurements were performed in downtown Paris (urban background sites) from January to November 2010. This unique dataset included non-methane hydrocarbons (NMHCs) and aromatic/oxygenated species (OVOCs) measured by a GC-FID (gas chromatograph with a flame ionization detector) and a PTR-MS (proton transfer reaction – mass spectrometer), respectively.
