Toyota develops tropospheric ozone-concentration simulator for South and East Asia

Green Car Congress

have developed a simulator able to predict tropospheric ozone concentrations across the whole of South and East Asia. Tropospheric ozone is the main cause of photochemical smog, an atmospheric pollutant harmful to human health and plant growth. Toyota Motor Corporation (TMC) and Toyota Central R&D Labs.,

TOAR shows present-day global ozone distribution and trends relevant to health; public database

Green Car Congress

Ozone levels across much of North America and Europe dropped significantly between 2000 and 2014. People living in parts of southern Europe, South Korea and southern Japan and China also experienced more than 15 days a year of ozone levels above 70 ppb. Trends in daily maximum ozone levels (known as 4MDA8) at urban and non-urban sites.

Study: 2/3 of aviation climate impact due to emissions other than CO2

Green Car Congress

The study was published in the journal Atmospheric Environment. Eleven years have passed since the last time a similar study was conducted, and there has been a strong growth in the aviation sector since then, particularly in Asia. Aviation accounts for 3.5% —Marianne Tronstad Lund, co-author. Pitari, M.J. Prather, R.

Study finds rising emissions of ozone-depleting CFC-11, banned by Montreal Protocol

Green Car Congress

Emissions of one of the chemicals most responsible for the Antarctic ozone hole are on the rise, despite an international treaty that required an end to its production in 2010, a new study by researchers at NOAA and their colleagues shows. Measurements from Hawaii indicate the sources of the increasing emissions are likely in eastern Asia.

Satellite method provides insight into ozone-NOx-VOCs sensitivity for different locations

Green Car Congress

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.

HALO research aircraft measuring the emissions of megacities in EmeRGe project

Green Car Congress

This scenario is particularly relevant in Asia, home to the world’s largest concentration of megacities. The transport and transformation of plumes from selected European and Asian major population centers (MPCs) will now be investigated with special focus on the rate of formation of ozone and aerosols. —Joohn Burrows.

Study finds global emissions of ethane and propane underestimated by more than 50%

Green Car Congress

When ethane and propane—the most abundant non-methane hydrocarbons (NMHC) in the atmosphere—mix with nitrogen oxides from vehicles and power plants they form tropospheric ozone—a key component of smog and directly linked to increases in mortality. —Professor Ally Lewis, a co-author of the study.
