The Asian monsoon circulation provides an effective pathway for pollution from Asia, India, and Indonesia to enter the global stratosphere, according to a new international study led by scientists at the National Center for Atmospheric Research (NCAR) in Boulder, Colo. NCAR scientist William Randel, the lead author.

They found that the level of emissions of regulated and unregulated pollutants in diesel exhaust depends on fuel, load, engine calibration, and exhaust aftertreatment technology. L/2004 calibration engines. L/2004 calibration engines. Unregulated pollutants also include ozone precursors and bioaccumulative and toxic compounds.

2010 engines emissions reduction relative to 2010, 2007, and 2004 US emission standards. For a number of the most important pollutants, levels were substantially lower than required by regulations. These reductions came while emissions of fine particles were also 92% lower than the 2010 standard 99% lower than 2004 emissions.

Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog. It is also not directly measurable from space due to the abundance of ozone higher in the atmosphere, which obscures measurements of surface ozone. —Jin et al.

systems in areas classified “Serious,” “Severe,” or “Extreme” for nonattainment of the ozone national ambient air quality standard (NAAQS). Vapor emissions from refueling, if allowed to escape, can contribute significantly to ground-level ozone, sometimes called smog, as well as to other types of harmful air pollution.
