CARB, NOAA, NASA and San Jose State University scientists team up to study ozone transported across Pacific

Green Car Congress

As California continues to reduce local sources of ozone, ozone entering the state from the Pacific makes up a larger fraction of measured ozone levels. An ozonesonde is a balloon which measures ozone from the surface to more than 10 kilometers above the ground.

EPA awards $6M in research funding to improve air quality models

Green Car Congress

The US Environmental Protection Agency (EPA) announced $5,959,842 million in research funding to nine institutions to improve air quality models used to simulate ozone, particulate matter (PM), regional haze, air toxics, and emerging pollutants. It will also inform the development of strategies for improving air quality.

Transient Plasma Systems says advances are bringing plasma ignition technology closer to commercialization

Green Car Congress

Advanced ignition technologies, such as those offered by TPS, have been widely recognized as enablers to achieving higher combustion efficiency and lower emissions for gasoline-powered engines. We believe the nanosecond pulsed power technology from TPS is unique and can be applied across a wide variety of applications.

Study: surface ozone in India in 2005 damaged 6M tonnes of crops, enough to feed 94M people in poverty

Green Car Congress

Ozone, the main component of smog, is a plant-damaging pollutant formed by emissions from vehicles, cooking stoves and other sources. New research shows that ozone pollution damaged millions of tons of wheat, rice, soybean and cotton crops in India in 2005. Surface ozone pollution in India damaged 6 million metric tons (6.7

Researchers fully characterize reaction that affects ground-level ozone formation; a small but significant impact on predictive models

Green Car Congress

The two combine in the atmosphere to make either nitric acid or peroxynitrous acid; the so-called branching ratio of these two chemicals is important in models of ozone production. A research team led by NASA’s Jet Propulsion Laboratory and the California Institute of Technology (Caltech), both in Pasadena, Calif.,

CARB releases results of multi-year E15 study; multiple air quality benefits with slight reduction in fuel economy

Green Car Congress

The California Air Resources Board (CARB) has released the results of a multiyear study evaluating exhaust emissions from the use of California Reformulated Gasoline (CaRFG) that contains 15 volume percent ethanol (E15). California currently limits the ethanol content of gasoline to 10 percent.

Study Links Springtime Ozone Increases Above Western North America to Emissions in Asia

Green Car Congress

Springtime ozone distributions for 1984, 1995–2008 in the mid-troposphere (3.0–8.0 Springtime ozone levels above western North America are rising primarily due to air flowing eastward from the Pacific Ocean, a trend that is largest when the air originates in Asia. The US EPA recently proposed new tougher ground-level ozone standards.
