Study finds pollution emitted near equator has biggest impact on global ozone

Green Car Congress

Since the 1980s, air pollution has increased worldwide, but it has increased at a much faster pace in regions close to the equator. They found that the increase in ozone burden due to the spatial distribution change slightly exceeds the combined influences of the increased emission magnitude and global methane.

New statistical method to detect ozone pollution hot spots and monitor instrument failure; combining PCA and MEWMA

Green Car Congress

A new statistical method developed by researchers at KAUST (King Abdullah University of Science and Technology, Saudi Arabia) can detect abnormal ozone levels within large bodies of monitored data. The monitoring methods can quickly and accurately detect ozone anomalies—localized spikes in ozone concentration indicated by sensor data.

Study quantifies impact of oil and gas emissions on Denver’s ozone problem

Green Car Congress

The first peer-reviewed study to directly quantify how emissions from oil and natural gas (O&NG) activities influence summertime tropospheric ozone (O 3 ) pollution in the Colorado Front Range confirms that chemical vapors from oil and gas activities are a significant contributor to the region’s chronic ozone problem.

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.

California Air Resources Board posts revised draft of strategy to reduce “Super Pollutants”

Green Car Congress

The California Air Resources Board (CARB) has posted a revised draft of California’s proposed Short-Lived Climate Pollutant (SLCP) Strategy. SLCPs are a category of pollutants which remain in the atmosphere for a relatively brief period, but have global warming potentials that are much higher than those of CO 2.

CARB fines Del Monte $2M for violations of OGV at Berth regulation

Green Car Congress

Through routine audits, CARB discovered that Del Monte’s chartered fleet calling at the Port of Hueneme for 2015-2016 did not meet the operational time limits for at least 50% of its visits and did not reduce its auxiliary engine power generation by 50%. These reductions decrease air pollution and the mortality rate of endangered whales.

Imaging study: air pollution impairs function of blood vessels in lungs

Green Car Congress

Air pollution impairs the function of blood vessels in the lungs, according to a study of more than 16,000 patients presented at EuroEcho-Imaging 2016. The study examined the effect of air pollution on pulmonary haemodynamics (blood flow) in a population and in individuals. Increases in PM 10 and PM 2.5
