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.

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.,

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.

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.

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.

Fast action on pollutants such as black carbon, ground-level ozone and methane may help limit near term global temperature rise and significantly increase the chances of keeping temperature rise below 2 °C (3.6 °F)—and The climate change benefit is estimated for a given year (2050) and human health and crop benefits are.

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.
