The System of Air Quality and Weather Forecasting And Research (SAFAR) on Thursday kickstarted its mission to identify and mark locations of 26 sources within the national capital which pollute the

Aerosol Optical Thickness (AOT) is a measure of solar spectral extinction. Long term AOT data analysis gives a picture of air quality for that location. This type of analysis is useful in the study of impact of urbanization on local climate. Aerosols are one of the most important but poorly understood factors that influence global climate change (IPCC, 2001). This calls for a need to regularly monitor the global aerosol distributions and study how they are changing over time.

Aerosols play an important role in climate change processes. Among the various aerosols, black carbon (BC) has been recognized as the second most important anthropogenic agent for climate change and the primary tracer for adverse health effects caused by air pollution. The increasing concentration of BC in the atmosphere has now become a matter of serious concern, especially in the high Himalayan glaciated region that has the most vulnerable ecosystem with pristine environment, rich biodiversity and pollution-free ambient air quality.

Albedo—a primary control on surface melt—varies considerably across the Greenland Ice Sheet yet the specific surface types that comprise its dark zone remain unquantified. Here we use UAV imagery to attribute seven distinct surface types to observed albedo along a 25 km transect dissecting the western, ablating sector of the ice sheet. Our results demonstrate that distributed surface impurities—an admixture of dust, black carbon and pigmented algae—explain 73% of the observed spatial variability in albedo and are responsible for the dark zone itself.

Tyre manufacturers’ body ATMA today said shortage of carbon black, a key ingredient for tyre manufacturing, in the domestic market has led to unplanned shutdown of factories.

The impact of black carbon, emitted by aeroplanes, on monsoon, glaciers and ozone layer is "uncertain", but its sustained emission could lead to warming of the atmosphere at 10-12 km altitude, the

Ships are an efficient way to move cargo, transporting approximately 80% of the world’s goods by volume, but ships also threaten human health, ecosystems, and the climate. This report focuses on the air and climate pollutant black carbon (BC).

Residential solid biomass cookstoves are important sources of aerosol emissions in India. Cookstove emissions rates are largely based on laboratory experiments conducted using the standard water-boiling test, but real-world emissions are often higher owing to different stove designs, fuels, and cooking methods. Constraining mass emissions factors (EFs) for prevalent cookstoves is important because they serve as inputs to bottom-up emissions inventories used to evaluate health and climate impacts.

Reducing greenhouse gas (GHG) emissions is the key to avoiding the most catastrophic impacts of climate change. Despite international shipping being excluded from the Paris Agreement, the International Maritime Organization (IMO) is developing its own strategy to reduce GHGs from ships.

Urban transit bus fleets are a significant source of air pollutant emissions, including black carbon, a harmful ultrafine particle and potent short-lived climate pollutant. Transit bus fleets are therefore an important target for accelerated transitions to clean engine technologies and fuels.
