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 …
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 …
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. Published black carbon emission factors can vary more than ten-fold, creating uncertainty in …
KOLKATA: The skyline on this part of the country turns grey by afternoon. By dusk, a thick layer of smog envelops the horizon. With winter setting in, millions living in rural and suburban India has many reasons to worry about, one of it being air pollution. The surroundings suffer from …
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). Original Source
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 issue. The past one year has been extremely fruitful for the fight against climate change. The Paris Agreement, finalised in …
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 …
This protocol was developed and subsequently tested in 2012–2015 by Nordic test and research institutes, with Danish Technological Institute as project manager. This protocol describes a potential standardized procedure for measurements of BC (Black Carbon) in terms of both EC (Elemental Carbon) and OC (Organic Carbon) from residential wood burning …
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 …
A new report indicates the combustion of fossil fuels is gravely affecting the alpine tundra's climate Fossil fuel and biomass, which are sources of black carbon, are accelerating glacier meltdown across the Himalayas and Tibetan Plateau, a new research report has found. The report by Chinese Academy of Sciences (CAS) …
The mass extinction of life 66 million years ago at the Cretaceous/Paleogene boundary, marked by the extinctions of dinosaurs and shallow marine organisms, is important because it led to the macroevolution of mammals and appearance of humans. The current hypothesis for the extinction is that an asteroid impact in present-day …
Long-term measurements (from August 2009 to December 2014) of aerosol black carbon mass concentration (MBC) and spectral aerosol optical depth (AOD) were carried out from a high-altitude location, Hanle in western trans-Himalaya as part of the Regional Aerosol Warming Experiment. Original Source
This document is the annual European Union (EU) emission inventory report to the United Nations Economic Commission for Europe (UNECE) Convention on Long-range Transboundary Air Pollution (CLRTAP). The report and its accompanying data constitute the official submission by the European Commission (EC) on behalf of the EU as a Party …
Emissions from solid fuels used for cooking cause ~4 million premature deaths per year. Advanced solid-fuel cookstoves are a potential solution, but they should be assessed by appropriate performance indicators, including biological effects. The researchers evaluated two categories of solid-fuel cookstoves for eight pollutant and four mutagenicity emission factors, correlated …
The North American Climate, Energy, and Environment Partnership was announced by Prime Minister Justin Trudeau, President Barack Obama, and President Enrique Peña Nieto on June 29, 2016, at the North American Leaders Summit in Ottawa, Canada. This Action Plan identifies the deliverables to be achieved and activities to be pursued …
Beijing and surrounding areas of China often suffer from choking smog. The Chinese government has made commitments to improving air quality and has achieved notable results in reducing emissions from the power and transportation sectors. However, new research indicates that the government could achieve dramatic air quality improvements with more …
Indications have emerged that ECOWAS countries may have started considering taking a giant stride to adopt the issues of regional harmonized low sulphur fuels by 2020. This came to fore last week in Abuja during the last ministerial regional summit, where the UNEP Programme Management Officer, Jane Akomu dropped the …
In order to understand the regional climate implications of aerosols over Indo Gangetic Plains (IGP), a major Indo-US field experiment, Ganges Valley Aerosol Experiment (GVAX) was conducted during 2011– 12. Atmospheric Radiation Measurement (ARM) mobile facility (AMF) was deployed at the northern Indo-Gangetic Plain over the high-altitude site, Manora Peak, …
In this paper, we evaluate the performance of the chemical transport model ‘CHIMERE’ over large Indian region (4–37.5°N; 67–88.5°E) for multiple years (2006, 2007 and 2008) by comparing the model simulations with concurrent aerosol measurements from different locations. Model simulated nearsurface black carbon mass concentrations agreed satisfactorily with measurements at …
